When I attempt to compile the program listed below I get the following message:
a.f90: In function 'MAIN__': a.f90:2: internal compiler error: in simplify_subreg, at simplify-rtx.c:4676 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions. The conditions were: 1. The August 3 version of gcc and gfortran were used. The problem does not occur with the July 27 version. 2. It was run on an SGI box under Debian Linux. I have not tested it on other processors. 3. The program was compiled with the flag "-fdefault-integer-8". It does not produce the error without this flag. 4. If I replace z = MAX(x,y) with i = MAX(j, k) the problem disappears. PROGRAM test z = MAX(x,y) END PROGRAM test -- Summary: internal compiler error: in simplify_subreg, at simplify-rtx.c:4676 Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: michael dot a dot richmond at nasa dot gov http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33006
