[cfe-dev] Problems with compiling ARMDisassembler.cpp with clang

[İsmail Dönmez]

Hey all;

I am doing a 2-stage clang-3.0rc3 build and while clang compiles
ARMDisassembler.cpp I get;

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

Seems to be clang is going out of memory while compiling this file, the
building VM has 2GB RAM and gcc 4.6 compiles it fine.

Any ideas?
