Bug ID: 65960
Summary: ICE in Cilk spawn with argument with non-trivial
constructor
Product: gcc
Version: 4.9.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: hvdieren at elis dot ugent.be
Target Milestone: ---
This code causes an ICE:
struct non_trivial {
int x;
non_trivial( int y ) : x( y ) { }
non_trivial( const non_trivial & s ) : x( s.x ) { }
~non_trivial() { }
};
int foo( non_trivial s );
int func( non_trivial s ) {
int x = cilk_spawn foo( s );
int y = 10;
cilk_sync;
return y - x;
}
Command line output:
$ g++-4.9.2 -fcilkplus struct.cc -o struct
struct.cc: In function '<built-in>':
struct.cc:28:31: internal compiler error: in lower_stmt, at gimple-low.c:370
int x = cilk_spawn foo( s );
