Summary: gfortran internal compiler error with malformed FLUSH
statement
Product: gcc
Version: 4.9.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: maddenp at colorado dot edu
Target Milestone: ---
This program has a syntax error (no unit specified) in the flush statement:
% cat p.f90
program p
implicit none
integer::i
flush (iostat=i)
end program p
% gfortran p.f90
f951: internal compiler error: Segmentation fault
[...]
% gfortran --version
GNU Fortran (Ubuntu 4.9.2-10ubuntu13) 4.9.2

Also, using the nightly snapshot I just downloaded (is this too new to be
useful?):
% ~/Desktop/gcc-trunk/bin/gfortran p.f90
f951: internal compiler error: Segmentation fault
0x5a78e0 ???
../sysdeps/x86_64/elf/start.S:113

% ~/Desktop/gcc-trunk/bin/gfortran --version
GNU Fortran (GCC) 6.0.0 20150723 (experimental) [trunk revision 226084]

My system:
% uname -a
Linux o 3.19.0-22-generic #22-Ubuntu SMP Tue Jun 16 17:15:15 UTC 2015 x86_64

I hope this is useful.
