Summary: ice in is_gimple_reg_type with -O2
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com

Created attachment 41306
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=41306&action=edit
gzipped C++ source code
The attached code, when compiled by today's gcc trunk and
compiler flag -c -O2, does this:
tcpserver.cc: In member function ‘virtual int TcpServer::EnableServer()’:
tcpserver.cc:361:1: internal compiler error: Segmentation fault
0xe5b59f crash_signal
../../trunk/gcc/toplev.c:337
0xe94aed is_gimple_reg_type
../../trunk/gcc/gimple-expr.h:75
0xe94aed verify_gimple_call
../../trunk/gcc/tree-cfg.c:3520
0xe94aed verify_gimple_stmt
../../trunk/gcc/tree-cfg.c:4738
The problem seems to have appeared between revision 246605 and 247438.
These two revisions are from the end of March and the start of May.
I'll try to reduce the code.
