Summary: gfortran crashes with segmentation fault
Product: gcc

Severity: normal

Run gfortran -c on this.
gfortran crashes with segmentation fault when compiling the attached file.
Problem is related to using MAXVAL of a rank-2 PARAMETER array as dimension for
a static variable.No special flags required, just gfortran -c. No assembly
generated. Running on Debian Jessie, tested with Debian's gcc 5.3.0 and 6.2.0
plus locally compiled 5.4.0. Compiler output from 6.2.0 is terse, from 5.4.0 is
pasted below:f951: internal compiler error: Segmentation fault
