[Bug c++/13392] New: ICE in convert_from_eh_region_ranges_1, at except.c:1133

["bkoz at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Trying to build LLVM with current mainline g++ fails. Interestingly, it only
fails at -O0, but at -O2 it works. Strange. 

%COMP.sh "--version"
g++ (GCC) 3.4 20031208 (experimental)

%COMP.sh "-c -O0" CommandLine.ii
/mnt/hd/src/llvm/lib/Support/CommandLine.cpp: In function `void
llvm::RemoveArgument(const char*, llvm::cl::Option*)':
/mnt/hd/src/llvm/lib/Support/CommandLine.cpp:77: internal compiler error: in
convert_from_eh_region_ranges_1, at except.c:1133
