Bug ID: 62129
Summary: internal compiler error: in output_constant, at
varasm.c:4755
Product: gcc
Version: 4.9.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: brooks at gcc dot gnu.org
Created attachment 33316
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33316&action=edit
Small example program.
(Google ref: b/17007254)
The following program causes an ICE in output_constant, at varasm.c:4755 on the
4.9 branch at r213772, and a similar ICE on trunk:
$ cat b17007254.cc
class Evaluator
{
int MakeChangelist ();
struct CreatorEntry
{
char *type;
int (Evaluator::*factory) ();
};
static constexpr CreatorEntry kCreators[] = { "",
&Evaluator::MakeChangelist };
};
constexpr Evaluator::CreatorEntry Evaluator::kCreators[];
$ gcc-archive/4.9/213772/bin/g++ --std=c++11 -c b17007254.cc
b17007254.cc:9:82: warning: deprecated conversion from string constant to
‘char*’ [-Wwrite-strings]
