2.0 frontend hangs

Hi,

While trying to compile ioquake3 (http://ioquake3.org/?page=get&method=source; use provided make-macosx-ub.sh wrapper to compile) with LLVM 2.0 for an experiment (seriously :-)), the 2.0 frontend hangs on a program file called code/server/sv_client.c. Apparently, it's stuck on line 2964 of gcc/gcc.c while waiting for some subprocess to complete. The 1.9 frontend however does not experience this problem and is able to compile.

How should I debug the frontend (currently recompiling with debugging support), as there are various threads/processes involved? Should I file a bug report?

Kind regards,
