Forgot the content of the conftest.F:

      program main
#ifndef __GNUC__
       choke me
#endif

      end

Created an attachment (id=8494)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=8494&action=view)
back trace tentative

I tried to isolate the bug and run in gdb. The issue appears as reported. After
terminating the process I executed a back-trace. Hope that it is helpful.

Can you try adding -v to see which program we are waiting on?
And then run that program with gdb?

gdb session, with backtrace, for f951

gdb session running the command f951 for which the wait is done in gfortran.

Looks like not a gfortran bug but a gmp one:
#0  0xdfb7bdac in __gmpn_mul_basecase () from /opt/csw/lib/libgmp.so.3
#1  0xdfb97840 in ?? () from /opt/csw/lib/libgmp.so.3
#2  0x00000006 in ?? ()
#3  0x0804759c in ?? ()
#4  0x080475c0 in ?? ()
#5  0x00000005 in ?? ()
#6  0xa0cba75d in ?? ()
#7  0xdfb7870d in __gmpn_mul () from /opt/csw/lib/libgmp.so.3

Could you make sure that the installed version of gmp is the correct one and is working?

The version of libgmp is 4.1.4. I'll contact the maintainer of the package to
know the build options, if he run the tests... and report back

The libgmp package maintainer supplied a new release for which all the gmp tests
are successful for the architecture in discussion. This fixes the bug.
