Summary: llvm-g++ EH code doesn't work with GCC 4.3 libgcc_s.so.1
Product: new-bugs
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: new bugs
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
CC: [email protected]
Compiling this test from the test-suite:
SingleSource/Regression/C++/EH/ctor_dtor_count.cpp
with llvm-g++ on an Ubuntu "Intrepid" box, where /lib/libgcc_s.so.1 is
built from gcc-4.3 sources, results in an executable that hangs when
executed.
I dug up a libgcc_s.so.1 from an older package compiled from gcc-4.2 sources,
and ran the same ctor_dtor_count executable without recompiling, forcing the
older library to be used using LD_PRELOAD, and it executed successfully.
Compiling ctor_dtor_count with regular g++-4.2 and running the executable with
the gcc-4.3 libgcc_s.so.1 does work.
I'm seeing this in both 32-bit and 64-bit executables.
Valgrind on the test executable found nothing interesting.
