I just tried to compile Fortran package LAPACK with the GNU Fortran compiler version 4.3 snapshot 20070601
The compiler said /home/dcb/gcc/20070601/results/bin/gfortran -g -O3 -Wall -c zlag2c.f -o zlag2c.o zlag2c.f: In function 'zlag2c': zlag2c.f:85: internal compiler error: in convert_move, at expr.c:361 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://gcc.gnu.org/bugs.html> for instructions. Source code attached. It compiles ok at -O2, so flag -O3 required. -- Summary: ice for legal code with -O3 Product: gcc Version: 4.3.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: dcb314 at hotmail dot com GCC host triplet: suse-linux-x86_64 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32194
