valgrind output running TextEdit
SUMMARY
valgrind 3.14rc2 is unable to launch TextEdit.app on macOS 10.12.6
STEPS TO REPRODUCE
1. just issue: valgrind /Applications/TextEdit.app
OBSERVED RESULT
- various text is output (attached), most notably:
==10558== Thread 2:
==10558== Invalid read of size 4
==10558== at 0x1077A52B1: ??? (in /usr/lib/system/libsystem_pthread.dylib)
==10558== by 0x1077A507C: ??? (in /usr/lib/system/libsystem_pthread.dylib)
==10558== Address 0x18 is not stack'd, malloc'd or (recently) free'd
==10558==
==10558==
==10558== Process terminating with default action of signal 11 (SIGSEGV)
==10558== Access not within mapped region at address 0x18
==10558== at 0x1077A52B1: ??? (in /usr/lib/system/libsystem_pthread.dylib)
==10558== by 0x1077A507C: ??? (in /usr/lib/system/libsystem_pthread.dylib)
then the memcheck-amd64-darwin process crashes, see attached backtrace.
EXPECTED RESULT
- to be able to launch TextEdit, probably the simplest Cocoa application.
SOFTWARE VERSIONS
macOS 10.12.6 (16G1510)
valgrind 3.14rc2
ADDITIONAL INFORMATION
- Maybe related to https://bugs.kde.org/show_bug.cgi?id=372779 ?
- I was able to run ls & cat with valgrind, so it's not totally broken
- Calculator.app fails in the same way.
- I suppose it could be identifying a real bug, but TextEdit is pretty
simple... and one supposes these days that Apple uses ASan & TSan...
