[Bug middle-end/30147] New: [regression 4.3] ICE in fold_convert with -O2

[burnus at gcc dot gnu dot org]

Today's gfortran crashes with "-c -O2" for the program below.
It works with today's 4.2.0 and with "-O".

I don't see right away whether this is a middle end or middle-end triggered
front-end problem.

input_cp2k_motion2.f90: In function 'create_neb_section':
input_cp2k_motion2.f90:12: internal compiler error: in fold_convert, at
