Bug ID: 65000
Summary: ICE in in expand_builtin_eh_common, at except.c:2072
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: larsbj at gullik dot net

With this test program I get an ICE:
-------
#include <boost/format.hpp>
void setGateLog()
{
boost::format fmt("%%");
fmt % 1;
}
-------
g++ --version
g++ (GCC) 5.0.0 20150210 (experimental) (as of revision 220578)

Removing -fno-sanitize-recover or compiling without optimization
removes the ICE.
I can provide pre-processed source if wanted.
