Bug ID: 60197
Summary: ICE with _Cilk_spawn in expression
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: reichelt at gcc dot gnu.org
The following valid(?) code snippet (compiled with "-fcilkplus") triggers
an ICE on trunk:
===========================================
int foo()
{
return (_Cilk_spawn foo()) + 1;
}
===========================================
gimplification failed:
