Re: [webkit-dev] jsc bus error EXC_BAD_ACCESS with jsc-only build on Mac
Hi, Hi, I’m trying to build jsc on my M1 Mac following the instructions at > https://trac.webkit.org/wiki/JSCOnly and https://webkit > .org/getting-started/ . > However when I run the built binary it exits immediately with a bus error > which lldb shows to be EXC_BAD_ACCESS. I'm also trying to build JSC on my M1 Mac and my experience is the *exact* same error as Laurence has reported above. When I run I get a bus error at the same location in the code: [27467]>DYLD_FRAMEWORK_PATH=/users/stevie/git/WebKit/WebKitBuild/JSCOnly/Debug > lldb WebKitBuild/JSCOnly/Debug/bin/jsc > (lldb) target create "WebKitBuild/JSCOnly/Debug/bin/jsc" > Current executable set to > '/Users/stevie/git/WebKit/WebKitBuild/JSCOnly/Debug/bin/jsc' > (arm64). > (lldb) target create Web > Available completions: > WebKitBuild/ > WebDriverTests/ > WebKit.xcworkspace/ > WebKitLibraries/ > Websites/ > (lldb) target create WebKitBuild/JSCOnly/Debug/b > Available completions: > WebKitBuild/JSCOnly/Debug/bmalloc/ > WebKitBuild/JSCOnly/Debug/bin/ > WebKitBuild/JSCOnly/Debug/build-webkit-options.txt > (lldb) target create WebKitBuild/JSCOnly/Debug/bin/jsc > Current executable set to > '/Users/stevie/git/WebKit/WebKitBuild/JSCOnly/Debug/bin/jsc' > (arm64). > (lldb) run > Process 86562 launched: > '/Users/stevie/git/WebKit/WebKitBuild/JSCOnly/Debug/bin/jsc' > (arm64) > Process 86562 stopped > * thread #1, queue = 'com.apple.main-thread', stop reason = EXC_BAD_ACCESS > (code=2, address=0x133804000) > frame #0: 0x00018696f248 libsystem_platform.dylib`_platform_memmove > + 168 > libsystem_platform.dylib`: > -> 0x18696f248 <+168>: stpq2, q3, [x0] > 0x18696f24c <+172>: subs x2, x2, #0x40 > 0x18696f250 <+176>: b.ls 0x18696f26c ; <+204> > 0x18696f254 <+180>: stpq0, q1, [x3] > Target 1: (jsc) stopped. > This is what 'image list' reports at this point: > (lldb) image list > [ 0] 7A464963-87D0-342F-BF0D-B030FC8488D4 0x0001 > /Users/stevie/git/WebKit/WebKitBuild/JSCOnly/Debug/bin/jsc > [ 1] F6DD3EC2-85A4-3AB1-8486-B189CD980EBE 0x0001865b > /usr/lib/dyld > [ 2] BDD21D2C-3C16-3379-9501-D64F8AFA3C0E 0x00010781c000 > /Users/stevie/git/WebKit > /WebKitBuild/JSCOnly/Debug/lib/JavaScriptCore.framework/Versions/1.0.0/JavaScriptCore > [ 3] A356C2AE-08AC-30C6-B3D2-89535B87B958 0x0001d1096000 > /usr/lib/libedit.3.dylib > [ 4] 27A49F84-CD29-3448-BE8C-ED4240A78C9C 0x0001b06d7000 > /usr/lib/libncurses.5.4.dylib > [ 5] BE250157-7A2B-39DA-B404-983D7989DFC6 0x0001935ae000 > /usr/lib/libSystem.B.dylib > [ 6] C0BCBAE5-4913-3D80-8E3A-9D4DEC1EA827 0x0001935a8000 > /usr/lib/system/libcache.dylib > [ 7] 0BA453ED-E5A2-3C2F-86F4-CFCFFA6C1879 0x000193563000 > /usr/lib/system/libcommonCrypto.dylib > [ 8] DE476BC5-36E2-3F7A-87C8-1EF2BE6ADFDA 0x00019358f000 > /usr/lib/system/libcompiler_rt.dylib > [ 9] 3DF60503-459B-3DA5-BD91-E72518FA9370 0x000193585000 > /usr/lib/system/libcopyfile.dylib > [ 10] 95C1D199-1B36-32B2-9BE7-5723A58D0D96 0x0001866a4000 > /usr/lib/system/libcorecrypto.dylib > [ 11] 7F973554-8168-35BF-AE86-2E9123E81BF7 0x00018678a000 > /usr/lib/system/libdispatch.dylib > [ 12] 72199A80-9C55-376D-8ECF-EE68AFA57B7A 0x000186945000 > /usr/lib/system/libdyld.dylib > [ 13] 291CFCDE-CF87-3F39-A3E3-36C4303BEC16 0x00019359e000 > /usr/lib/system/libkeymgr.dylib > [ 14] DD2A9F47-7F80-344C-B6FE-82682F8AAB4A 0x00019353b000 > /usr/lib/system/libmacho.dylib > [ 15] 158A39C2-F9C6-32CA-845B-F1DFB711718A 0x000192a1c000 > /usr/lib/system/libquarantine.dylib > [ 16] 92A7E10F-1F6C-30D5-9C44-D42352D3A674 0x00019359b000 > /usr/lib/system/libremovefile.dylib > [ 17] B8B21C7C-4530-3EA2-AB35-BA98B82F33D0 0x00018c0bc000 > /usr/lib/system/libsystem_asl.dylib > [ 18] E9F1A3B9-AE38-3F4C-BF14-8A6E012AD36C 0x000186639000 > /usr/lib/system/libsystem_blocks.dylib > [ 19] 49477E07-E77B-332F-B98D-79CA210A866D 0x0001867d5000 > /usr/lib/system/libsystem_c.dylib > [ 20] 2EA02C23-E13C-39AE-B850-82CEABACE7A6 0x000193593000 > /usr/lib/system/libsystem_collections.dylib > [ 21] D57D8736-2800-3066-82D4-C433A2DC10C4 0x000191bf6000 > /usr/lib/system/libsystem_configuration.dylib > [ 22] C9DB5B40-6F90-348A-A518-3ACFB49B39FE 0x000190c34000 > /usr/lib/system/libsystem_containermanager.dylib > [ 23] 324A6A0A-BBDE-3257-9A75-6A74C85E3430 0x0001931d2000 > /usr/lib/system/libsystem_coreservices.dylib > [ 24] 8DB1E11F-85AB-3699-AD96-228BE7D8C715 0x000189d5b000 > /usr/lib/system/libsystem_darwin.dylib > [ 25] 0395D567-DBD9-3F03-A9E0-A0969963A834 0x00024d32a000 > /usr/lib/system/libsystem_darwindirectory.dylib > [ 26] 4D030E4B-27FC-3C22-8467-A8CAFECA7761 0x00019359f000 > /usr/lib/system/libsystem_dnssd.dylib > [ 27] 6C663441-D4D5-361C-ABE7-B68D7B6E5B9B 0x00024d32e000 > /usr/lib/system/libsystem_eligibility.dylib > [ 28] D8AF5585-B9E4-38C0-B48B-CFD5C13DEB82 0x0001867d2000 > /usr/lib/system/libsystem_featureflags.dylib > [ 29] 615EAFA2-4446-399
