[Bug fortran/26717] New: gfortran: ICE at tree-complex.c:133 with -O -ffast-math in LAPACK,

[anlauf at gmx dot de]

Hi,

compiling LAPACK with -O -ffast-math leads to an ICE
in LAPACK's csptri.f and csytri.f:

% gfortran -O -ffast-math -c csptri.f
csptri.f: In function 'csptri':
csptri.f:1: internal compiler error: in find_lattice_value, at
tree-complex.c:133

The same error is encountered in the other file.

Cheers,
-ha
