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. -- Summary: internal compiler error -ff2c Product: gcc Version: 4.1.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: tim dot bevan at 1spatial dot com GCC host triplet: i586-suse-linux GCC target triplet: i586-suse-linux http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30979
