[Qemu-devel] Latest git version failed to run 403.gcc benchmark in SPEC CPU2006

I'm trying to run benchmarks from SPEC CPU2006 compiled for SPARC on
top of qemu-sparc32plus. However, several benchmarks failed to get the
One of the failed benchmarks, 403.gcc, runs for a while and then print
an error message and exit. However, the same compiled gcc binary for
SPARC runs quite well in Simics(a commercial emulator) and give the
correct result. So I think there may be a bug in Qemu.
Has anyone meet the same kind of problem before?
I can do some debug, but I have no clue on how to do it. Could anyone
please give me some hint on this? I have read the source code, but
find it really hard to track down guest program miss-behavior problem.
BTW, when I use sparc-linux-gdb with qemu-sparc32plus, it connect, but
give the wrong value when print local variables. So, I'm really lost.
Can anyone confirm on this, or I'm doing it the wrong way?
As of next Tuesday, C will be flushed in favor of COBOL.
Please update your programs.
