Bug ID: 75860
Summary: Segmentation violation in tree_check while compiling
firefox 48
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: zeccav at gmail dot com
Target Milestone: ---
While compiling firefox version 48 with the trunk gcc 7.0 I get the following
segmentation violation
tree.h:3022 is "if (TREE_CODE (__t) != __c)"
Maybe __t is NULL?
I put MAJOR severity because this happens compiling a real software,
not a custom built fragment.
