The testcase for bug 38582 causes a new failure in gcc trunk, an internal
compiler error (see summary). The revision is
Last Changed Rev: 152847
Last Changed Date: 2009-10-15 16:12:03 +0100 (Thu, 15 Oct 2009)
To reproduce, execute the following in the gcc build directory:
./f951 testcase.f90 -ffree-line-length-512 -g -ffree-form -ftime-report
-funroll-loops -O3
I'll attach the testcase to this bug as well.
I've briefly looked at it and this appears to be an integer overflow. In
account_vars_for_block, we end up with new_sv_num == 65576, and
triangular_index overflows.
