This was almost certainly fixed on 2006/11/09, by this patch to bugpoint: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20061106/039715.html

Because we don't use 3.3 anymore, it might be okay to close this as "won't fix". If you're comfortable that it's okay with 4.x gcc, that is.

[llvmbot]

LLVM was compiled with gcc 3.3 in that case. I was seeing strange memory related (detected leaks) errors with LLVM on x86 when compiled with gcc 3.3 that didn't appear when compiled with later gccs. This could be another symptom of gcc 3.3 brokenness.

[isanbard]

This should be revisited. Does it still crash? It didn't crash for me when I updated the BC file.

An ASM vesion of the attached bytecode file. It's out of date now.
