> Please see http://kinoko.c.u-tokyo.ac.jp/~duraid/stdcxxissues if you want to try and reproduce this. There, you will find the following files:
> DataStructure.cpp: the code I'm trying to build (it is a part of LLVM, http://www.llvm.org)
> Note: the problem is the const keyword on line 694 (const GlobalValue *V = Src[0]; ) - removing that keyword allows the file to be compiled, but I think the const keyword should be legal there.
> algorithmcc_bug.i: (preprocessed source: you should be able to compile this with aCC as follows:
> aCC -D__STDC_LIMIT_MACROS -AA -DNDEBUG -D_RWSTDDEBUG     -D_RWSTD_USE_CONFIG   +d  +w +W392 +W655 +W684 +W818 +W819 +W849 +W2193 +W2236 +W2261 +W2401 +W2487 +O2  -c algorithmcc_bug.i
> compile_log: what I see when trying to compile DataStructure.cpp with the const keyword present (grep for the error #2304)
> If you would like an account on the machine where I see this, just let me know!
