>Description:
Bootstrapping the current trunk sources fails if CFLAGS contains -march=pentium4 (all lower architecture classes work).  The compiler seems to be caught in an endless loop and only finishes when all memory is exhausted (>2 GB in my case).

The file in question is gcc/libjava/libltdl/ltdl.c.
>How-To-Repeat:
I don't think it's necessary to attach a file.  The stock sources will be.  Just run

  make CFLAGS="-O2 -march=pentium4 -g"

It's probably possible to build the compiler normally and use it to compile ltdl.c then.
