Bug #: 50790 Summary: ICE in copy_constant on divide by expression that evaluates to zero Classification: Unclassified Product: gcc Version: 4.6.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: fortran AssignedTo: unassig...@gcc.gnu.org ReportedBy: jonathan.h...@stfc.ac.uk The following code produces an ICE for me: program test implicit none integer :: i i = 3 print *, "chk", 3/(i-i) end program test This should presumably produce Error: Division by zero at compile time (or run time if we're not being clever). Produced with: GNU Fortran (Debian 4.6.1-4) 4.6.1 Copyright (C) 2011 Free Software Foundation, Inc. Thanks, Jonathan.
