Summary: OpenMP task construct fails to instantiate copy
constructor(same as Bug 36523)
Product: gcc
Version: 4.5.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: bbe...@gmail.com
The same bug like in gcc 4.4.0 Bug 36523.
The following test case fails with a linker error. It compiles okay with the
pragma omp task line removed.
$ cat task.cpp
template<typename T>
struct A
{
A() { }
A(const A&) { }
void foo() { }
};
int main()
{
A<int> a;
#pragma omp task
a.foo();
return 0;
}
$ g++ -fopenmp -Wall task.cpp
/tmp/cc5epalM.o: In function `main.omp_cpyfn.1':
task.cpp:(.text+0x73): undefined reference to `A<int>::A(A<int> const&)'
collect2: ld returned 1 exit status
$ g++ -v
Using built-in specs.
