Hi LLVMers,

  there were a gcc ICE problem discussed in current mail list. 

  Chris was right here:
  saying that the PR 12544 is not really the corresponding issue :)

  The correct one is PR 13392:
  Interesting fact is that -O2 (or -O3) goes somehow around this 
  problem. It looks like -O2 is not used here:

/home/vak/ssrc/llvm/mklib --tag=disable-shared --silent --mode=compile g++ -c -I/home/vak/ssrc/llvm/lib/Support -I/home/vak/ssrc/llvm/lib/Support -I/home/vak/ssrc/llvm/include -I/home/vak/ssrc/llvm/include -I../../include -I/home/vak/ssrc/llvm/include -D_GNU_SOURCE -D__STDC_LIMIT_MACROS  -Wall -W -Wwrite-strings -Wno-unused -g  -D_DEBUG CommandLine.cpp -o /home/vak/ssrc/llvm/lib/Support/Debug/CommandLine.lo

and in some other LLVM libs. Is it intended?

BTW, adding -O2 really does help.

Any comments?

kind regards,
Valery A.Khamenya
