Bug ID: 66347
Summary: Seg fault (ICE) on compile
Product: gcc
Version: 5.1.1
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: wbrisken at gmail dot com
Target Milestone: ---
Created attachment 35656

fortran test case causing ICE
I have an example of code that would compile without problem with gfortran
4.4.7 and gfortran 4.8.4 but causes ICE on the recent gfortran SVN 5.1 branch.
This is not my own code and I know little of fortran programming so apologies
if the code is ugly or if it is not a minimal test case.
Compiler version causing crash:
wbrisken@shiitake sked> gfortran -v
Using built-in specs.
COLLECT_GCC=gfortran
COLLECT_LTO_WRAPPER=/export/home/shiitake/gcc/libexec/gcc/x86_64-unknown-linux-gnu/5.1.1/lto-wrapper

Configured with: ../gcc/configure --prefix=/export/home/shiitake/gcc/
Thread model: posix
gcc version 5.1.1 20150523 (GCC)

Preprocessed output file:
Not generated. Perhaps Seg Fault happened too early.
I hope this bug report is useful and complete.
