[Bug fortran/30979] New: internal compiler error -ff2c

[tim dot bevan at 1spatial dot com]

gcc version 4.1.0 (SUSE Linux)

Trivial file fails to compile with -ff2c:

gcc orient.f -ff2c -c -O -Wall -o orient.o
orient.f: In function 'angnrm':
orient.f:1: internal compiler error: in emit_move_insn, at expr.c:3158
Please submit a full bug report,
with preprocessed source if appropriate.

Omitting the -ff2c compiles the file. 

A different machine compiles this fine:
gcc version 4.0.2 20050901 (prerelease) (SUSE Linux)
- although the output code differs depending on the -ff2c option.

Works, in terms of compiles, with gfortran-4.3 (svn version, 20070220).
Did you try the latest 4.1.2 release?

Unfortunately it is not possible to test that here at the moment. This is not
critical as I can avoid needing this code. Not sure if we do actually need to
specify the -ff2c flag anyway, I have a report that we needed it to compile
other code with the earlier compiler.

Having got gcc 4.1.3 (which supplied 4.1.2 prerelease) and some newer version
of the GMP library installed.

gcc --version
gcc (GCC) 4.1.2 20061115 (prerelease) (SUSE Linux)

The problem still occurs 

gcc orient.f -ff2c -c -O -Wall -o orient.o
orient.f: In function 'angnrm':
orient.f:1: internal compiler error: in emit_move_insn, at expr.c:3162
