15285 – [3.4/4.0 regression] instantiate_type ICE when forming pointer to template function (original) (raw)

Description Robert Evans 2004-05-04 19:52:02 UTC

The compiler throws an ICE when trying to form a pointer to an instance of a template function from within a different template function. This worked in gcc-3.3.3 and is also broken in the mainline.

tf.C*************

void foo(void (*func)()) {}

template void bar() {}

template void baz() { foo(&bar); }

$ g++ tf.C tf.C: In member function `void Class::foo(Object*)': tf.C🔞 internal compiler error: in instantiate_type, at cp/class.c:6164
