Description Jan Kratochvil 2011-07-21 07:23:50 UTC 
Description of problem:
For any newly built binaries valgrind fails.

Version-Release number of selected component (if applicable):
valgrind-3.6.1-4.fc16.x86_64
binutils-2.21.53.0.1-1.fc16.x86_64

How reproducible:
Always.

Steps to Reproduce:
echo 'main(){exit(0);}'|gcc -x c -
valgrind ./a.out 

Actual results:
--2555-- Warning: DWARF2 CFI reader: unhandled DW_OP_ opcode 0x2a
valgrind: m_debuginfo/readdwarf.c:2391 (copy_convert_CfiExpr_tree): Assertion 'srcix >= 0 && srcix < VG_(sizeXA)(srcxa)' failed.
==2555==    at 0x3804AD06: ??? (in /usr/lib64/valgrind/memcheck-amd64-linux)

Expected results:
No such message.

Additional info:
Sure it is probably due to the new plt .eh_frame unwinder.

Apparently fixed upstream, though the fix has minor issues.
Comment 2 Jan Kratochvil 2011-07-24 07:05:28 UTC 
Works for me now.
