[Bug target/42159] app compiled with 4.4.2 SIGABRTs after a trivial nested throw/stack unwinding

--- Comment #14 from vlad at demoninsight dot com 2009-12-01 05:50 --- (In reply to comment #13) (In reply to comment #12) Compile-time. configure with --enable-checking=release to turn off checks that are enabled by default in pre-release builds, that will give a better comparison between the 4.4.2 release and 4.5 snapshot Thank you for a useful tip. I have re-built the same snapshot: Using built-in specs.

With 4.4.2 and 4.5 snapshot installed in parallel dirs, I ran the same build in two shells and simply pointing the builder from one version to another. The times are quite reproducible: 4.4.2: ~ 337 sec 4.5: ~ 466 sec (averages of two runs each). So, 4.5 snapshot is 40% slower at compile time. This is quite a bit better than without --enable-checking=release (which was close to 2x slower) but seems a tad heavy price to pay to just have exceptions working ... -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42159

--- Comment #9 from vlad at demoninsight dot com 2009-11-29 16:04 --- Well, I think my scheme worked: I have succeeded in reverse engineering the 4.4.2 fink scripts into something I could use to build 4.5 trunk against the prerequisite libs installed via fink.

--- Comment #8 from vlad at demoninsight dot com 2009-11-28 06:42 --- I am somewhat unsure about what our best course of action is at this point. Can we discuss this in gnu forums? Could I help by providing diagnostics? I'd like to use 4.4.x for its OpenMP support etc in preference to the xcode version. I see that many (all?) prerequisites for building gcc are available through fink: gmp, ppl, fmpr, etc. I wonder if I could leverage fink to get all of the dependencies and then try building the current against those. Jack, since you're the maintainer of the fink package you probably build it all the time. Would be able to point in the right direction with the above idea, assuming a vanilla fink install in /sw? I feel lost among the many svn branches already... -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42159

--- Comment #3 from vlad at demoninsight dot com 2009-11-24 15:48 --- (In reply to comment #1) This bug doesn't appear to be present in current gcc trunk on x86_64-apple-darwin10. Jack, how should I interpret your comment? That all is well in 4.4.3 branch or something? Or that you cannot reproduce it on your end in 4.4.2? If one wanted to leverage darwinports how would one get a 4.4.x version of gcc that does not have this issue? It seems like a basic failure of exception hanlding mechanism. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42159
