I'll try with 7.0 instead. Interestingly, it works ok on alpha-dec-osf4.0f: it seems to be due to the fact that V5.1B supports 128-bit long double, while V4.0F does not. -- Summary: [4.5 regression] cc1 SEGV compiling maxval_r16.c Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: target AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: ro at gcc dot gnu dot org GCC build triplet: alpha-dec-osf5.1b GCC host triplet: alpha-dec-osf5.1b GCC target triplet: alpha-dec-osf5.1b http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41930
