[racket-users] Drracket crashing on startup
This morning, when I attempted to start Drracket from a terminal (I'm using Archlinux, 64 bit, with the most recently upgraded versions of Racket and Drracket), I obtained this error: SIGSEGV MAPERR si_code 1 fault on addr 0xe8042caa [2]26140 abort (core dumped) drracket A bit of web searching reveals that this error is not unknown, but I can't find the solution. What I believe I can do is to log out and back in again, but that's a pain. Does anybody here know how I can overcome this error other than restarting my login session?

[racket-users] DrRacket crashing, preserved syntax properties, and (exn-message #t) ?
Hello, I'm trying out the new feature for marking syntax properties to be preserved when compiled. It runs perfectly well on the command line, but it crashes DrRacket. If I turn off background expansion, it doesn't crash immediately, but it does crash when I run it or click check-syntax. So then I tried running the macro stepper on the file. At some point in the middle of the steps, a DrRacket internal Error window came up with this message: exn-message: contract violation expected: exn? given: #t context...: /Applications/Racket/2016-04-16/Racket v6.5.0.2/share/pkgs/macro-debugger/macro-debugger/view/step-display.rkt:66:4: add-error method in step-display% ...browser/util.rkt:18:9 /Applications/Racket/2016-04-16/Racket v6.5.0.2/share/pkgs/macro-debugger/macro-debugger/view/stepper.rkt:438:4: update* method in macro-stepper-widget% /Applications/Racket/2016-04-16/Racket v6.5.0.2/share/pkgs/macro-debugger/macro-debugger/view/stepper.rkt:400:31 .../more-scheme.rkt:261:28 /Applications/Racket/2016-04-16/Racket v6.5.0.2/share/pkgs/macro-debugger/macro-debugger/view/stepper.rkt:369:24 Does this mean anything?

[racket-users] DrRacket crashing?
I have no idea what's been happening, but in the past half hour or so DrRacket has crashed on me (I think) 6 times. I don't know if this will help but here is what was in the error window that my computer gave me: Process: DrRacket [20469] Path:/Applications/Racket/*/DrRacket.app/Contents/MacOS/DrRacket Identifier: org.racket-lang.DrRacket Version: 6.2.900.10 (6.2.900.10) Code Type: X86-64 (Native) Parent Process: launchd [165] Responsible: DrRacket [20469] User ID: 502 Date/Time: 2015-08-21 20:00:33.149 -0400 OS Version: Mac OS X 10.9.5 (13F1096) Report Version: 11 Anonymous UUID: 8ABEA743-D90C-CA8D-137C-2A4F0679E863 Sleep/Wake UUID: 09B771D9-37AF-4A41-A852-C8AC90205883 Crashed Thread: 7 Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0x0008 VM Regions Near 0x8: --> __TEXT 00010211e000-000102126000 [ 32K] r-x/rwx SM=COW /Applications/Racket/*/DrRacket.app/Contents/MacOS/DrRacket Thread 0:: Dispatch queue: com.apple.main-thread 0 libsystem_kernel.dylib 0x7fff9039da1a mach_msg_trap + 10 1 libsystem_kernel.dylib 0x7fff9039cd18 mach_msg + 64 2 com.apple.CoreGraphics 0x7fff8e73a74b _CGSSynchronizeWindowBackingStore + 97 3 com.apple.CoreGraphics 0x7fff8e6bc24c _CGSLockWindow + 3765 4 com.apple.CoreGraphics 0x7fff8e6bb15f CGSDeviceLock + 240 5 libRIP.A.dylib 0x7fff8daf3487 ripd_Lock + 43 6 libRIP.A.dylib 0x7fff8daf3027 RIPLayerBltShape + 463 7 libRIP.A.dylib 0x7fff8daf1468 ripc_Render + 304 8 libRIP.A.dylib 0x7fff8daed3b9 ripc_DrawRects + 399 9 com.apple.CoreGraphics 0x7fff8e6b7afa CGContextFillRects + 96 10 com.apple.AppKit0x7fff94b52d46 NSRectFillUsingOperation + 299 11 com.apple.AppKit0x7fff94c0f0bd NSDrawWindowBackground + 253 12 com.apple.AppKit0x7fff94b31d04 -[NSThemeFrame drawWindowBackgroundRect:] + 129 13 com.apple.AppKit0x7fff94b315d0 -[NSFrameView drawThemeContentFill:inView:] + 293 14 com.apple.AppKit0x7fff94c0e715 -[NSFrameView drawRect:] + 1124 15 com.apple.AppKit0x7fff94c0e28a -[NSThemeFrame drawRect:] + 302 16 com.apple.AppKit0x7fff94b2d0b1 -[NSView _drawRect:clip:] + 3846 17 com.apple.AppKit0x7fff94b2a03c -[NSView _recursiveDisplayRectIfNeededIgnoringOpacity:isVisibleRect:rectIsVisibleRectForView:topView:] + 3199 18 com.apple.AppKit0x7fff94b28eb1 -[NSThemeFrame _recursiveDisplayRectIfNeededIgnoringOpacity:isVisibleRect:rectIsVisibleRectForView:topView:] + 314 19 com.apple.AppKit0x7fff94b25e9f -[NSView _displayRectIgnoringOpacity:isVisibleRect:rectIsVisibleRectForView:] + 2828 20 com.apple.AppKit0x7fff94b052da -[NSView displayIfNeeded] + 1680 21 Racket 0x00010249ef5c ffi_call_unix64 + 76 22 Racket 0x00010249f82d ffi_call + 973 23 Racket 0x00010248b460 ffi_do_call + 2192 24 Racket 0x00010248abac ffi_do_call_after_stack_check + 268 25 ??? 0x0001035eb959 0 + 4351506777 26 Racket 0x000102191d20 scheme_do_eval + 13360 27 Racket 0x00010219286c _scheme_apply_multi_from_native + 364 28 ??? 0x00010357f01e 0 + 4351062046 29 ??? 0x00010358123d 0 + 4351070781 30 ??? 0x00010358123d 0 + 4351070781 31 Racket 0x000102191d20 scheme_do_eval + 13360 32 Racket 0x0001021c87ff scheme_finish_apply_for_prompt + 639 33 Racket 0x0001021c8b80 scheme_apply_for_prompt + 112 34 Racket 0x0001021b8e94 call_with_prompt + 2532 35 ??? 0x0001035741d5 0 + 4351017429 36 Racket 0x000102191d20 scheme_do_eval + 13360 37 Racket 0x0001021c87ff scheme_finish_apply_for_prompt + 639 38 Racket 0x0001021c8b80 scheme_apply_for_prompt + 112 39 Racket 0x0001021b8e94 call_with_prompt + 2532 40 ??? 0x0001035741d5 0 + 4351017429 41 ??? 0x0001035816eb 0 + 4351071979 42 Racket 0x000102191d20 scheme_do_eval + 13360 43 Racket
