Summary: ICE: tree code 'template_type_parm' is not supported
in gimple streams with -flto
Product: gcc
Version: lto
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: scov...@gmail.com
The following minimal test case makes x86_64-unknown-linux-gnu-gcc-4.5.1 ICE
when the -flto flag is supplied:
$ cat > lto-bug.h <<EOF
#pragma interface
template<class T> struct foo;
template<class T>
struct foo<T*&> : foo<T&> {
foo<T*&>(T* t) : foo<T&>(*t) { }
};
EOF
$ cat > lto-bug.C <<EOF
#pragma implementation "lto-bug.h"
#include "lto-bug.h"
EOF
$ gcc-4.5.1 -flto lto-bug.C
In file included from lto-bug.C:2:0:
lto-bug.h:6:2: internal compiler error: tree code ‘template_type_parm’ is not
supported in gimple streams
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.
Removing anything at all makes the ICE disappear
This seemed similar to bug #45959, but applying the patch mentioned there to
gcc-4.5.1-src/gcc/cp/pt.c:11322 does not help so I'm filing a new bug for this.
