Bug ID: 60967
Summary: ICE with range for in template function with C++11 and
cilkplus
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: florent.hivert at lri dot fr
It is not possible to use a range for in a template function (or member
function by the way) when compiling with C++11 and Cilkplus. The following code
int container[] = {};
template <class foo>
void bar() {
for (int &v : container) { }
}
when compiled with
/opt/gcc-cilk/bin/g++ -std=c++11 -fcilkplus bug.cpp
triggers an internal compiler error:
bug.cpp: In function ‘void bar()’:
bug.cpp:4:30: internal compiler error: tree check: expected for_stmt or
cilk_for_stmt, have range_for_stmt in cp_parser_for, at cp/parser.c:9872
for (int &v : container) { }

Everything is Ok if one remove the -fcilkplus option or the template line.
