[Bug fortran/42723] New: Bootstrapping Fortran with GCC 4.4.2 fails on Solaris 5.10: "f951: internal compiler error: Arithmetic Exception"

["Roger dot Jeurninck at home dot nl" <gcc-bugzilla at gcc dot gnu dot org>]

Building the GCC compiler for the language "Fortran" fails in bootstrapping
mode. Strangely, I am able to build the Fortran compiler in native
non-bootstrapping mode.

If I do start the build in bootstrapping mode, it finally fails with the
following error (I will attach the complete log):

configure: failed program was:

|       end program foo
***************************************************

Running the testsuite on the bootstrapped build will (obviously) give very poor
results for the fortran part. This confirms that the fortran compiler is messed
up seriously.

Hope you can help me as I'm completely stuck on this one.
thanks,

Roger
