System: NetBSD 6.99.40
Architecture: x86_64
Machine: amd64
>Description:
I've tried compiling wip/gambatte-dev. I've configured pkgsrc to use
clang, but in this case the package seems to use g++ anyway.

Building immediately stops with:

I've looked with ktrace, it's cc1plus reporting that error (forked by
g++).

 I could build the pkg just fine (and it even works) on an amd64 machine
 I just updated.

 I also could compile the cpu.ii file with the command line you showed.

 Can you update your machine and try again? There have been a few libc
 string fixes in the last week or so.

 I already had all of these.

 martin could reproduce the problem after using clang to compile gcc,
 i.e. using build.sh with '-V DBG="-O2 -g" -V MKLLVM=yes -V
 HAVE_LLVM=yes -V MKLIBCXX=yes'. For him, the problem already appears in
 the pcre package.

 The gcc bug was closed; I've filed a bug against clang:
