$ gcc --version
i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5666) (dot 3)
I am building gcc trunk on OS X using gcc 4.2.1. Everything goes swimmingly until the command below, which spins the CPU and seems to make no progress. I have seen it run for over an hour. The output file reaches 28,101,392 bytes and stops.
A build of gcc-4_8-branch exhibits the same behavior, except that the output file is . O2ggnu++0x.gch
Suggestions? I attached to the process with gdb to obtain a backtrace, in case that helps, see below. It seems stuck in mpfr, but it's not clear if that's an issue with mpfr or how it's called. Or built. Or something.
Relevant prerequisite versions I used are:
$ ls *{gmp,mpfr,mpc,isl,cloog}*
cloog-0.18.0.tar.gz gmp-5.1.2.tar.lz mpc-1.0.1.tar.gz
gmp-5.1.2.tar.bz2 isl-0.11.1.tar.bz2 mpfr-3.1.2.tar.gz
Further details on request. Unfortunately, it's easy to replicate.
Many thanks.
