Mon 16 Feb 2015 12:04:24 PM UTC, comment #2: Commit "Fail when out of memory in set_hunkmax()" in version 2.7.2 fixes the segmentation fault, however it does not fix the insane memory consumption (8 GB on my 4 GB memory machine according to valgrind.)	Jean Delvare <khali>
Tue 20 Jan 2015 11:46:55 AM UTC, comment #1: Should be fixed in commit "Fail when out of memory in set_hunkmax()" now.	Andreas Gruenbacher <agruen>
Tue 20 Jan 2015 07:20:52 AM UTC, original submission: Got an other issue which output this before segfault: patching file util.h Ran out of memory using Plan A -- trying again... patching file util.h Segmentation fault Use it as 'patch util.h --input crash.diff'.	Laszlo Boszormenyi (GCS) <gcs>
