The fortran compiler (f951) seem to hang even for a simple hello world program

First question: Do you use the trunk or some branch? From your email,
I'd assume that you use the trunk, but "b-cilkplus-gcc" rather implies
that you are using some branch.
Looking at the backtrace, it seems as if your GMP (GNU Multiprecision
[integer] Library) and/or MPFR (multi-precision floating-point library)
is not correctly working, e.g. you might use a different library version
at run time than you compiled against. The problem could be either f951
-> MPFR or MFPR -> GMP. Or it could be something different. In any case,
the failure happens very early in the f951 when the some variables are
initialized - which is before the parser even has started.

I tried a small hello world program and it was also hanging. I tried to gdb it
and here is the backtrace. My current revision is at r198424. My previous
revision was at r198143 and I believe things were working fine there.
Here is the test program:
PRINT *, 'Hello, world!'
END
Here is the back trace:
