Actually, I am confused: From that comment it sounds as if 20100921 does not
have the bug 45746 - but it has been reported using 20100921 and a comment by
Dominique indicates that it never worked with GCC 4.5/4.6 but it only worked
for a while on the fortran-dev branch.

Any reason why you think that this will be the case?

Such bugs are usually an indication for not properly initialized memory.
Especially when it happens, it helps if one can try valgrind on the file:

  valgrind `gfortran -v 2>&1 <other commandline options> | grep f951`

Memory related errors tend to show up only on few machines and in irregular
patterns, which makes finding them difficult.
