Bug ID: 59403
Summary: [4.8.2] Segmentation fault in crash_signal
Product: gcc
Version: 4.8.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: boaz at alum dot mit.edu
Our project compiles OK with 4.8.1 ; however switching to 4.8.2 causes g++ to
segfault !! When "-v -save-temps" is added to the command line options, the
compilation passes OK !!
