Bug ID: 76490
Summary: when use -O2 -fcheck-founds compiler appears to hang
and consumes all memory
Product: gcc
Version: 5.4.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: fortran
Assignee: unassigned at gcc dot gnu.org
Reporter: urbanjost at comcast dot net
Target Milestone: ---
Routine that has compiled for years with gfortran 4.9.6 and older versions now
hangs compiler when -O2 -fbound-checks is used. Running on Cygwin with 5.4.0
version. Reduced to simple test case. Might be duplicate of other reports of
all memory being consumed but none seems to match exactly. Small test program
wrapped in a bash(1) shell attached.
