Description Thor Nolen 2001-08-05 15:15:20 EDT
funcptr2.cc - Resolving template functions through ?:.  This
problem showed up when we tried to compile under GCC 2.96-85.  It
doesn't happen under GCC 2.91.66.  The compiler crashes with an
internal error (#980715) when you try to compile code that takes the
address of a static member function.  The problem is that you can't
use ?: to decide between templated function pointers within a function
call.  If you break out the ?: into an if/else the problem goes away.

Comment 2 Jakub Jelinek 2001-08-08 13:04:21 EDT
This was fixed with
http://gcc.gnu.org/ml/gcc-patches/2001-07/msg01723.html
in 3.0.1 and it fixes it for 2.96-RH too, will put it into 2.96-96.
Comment 3 Jakub Jelinek 2001-08-09 06:28:04 EDT
Fixed is unclear here, because according to Jason Merrill, it is unclear whether this is valid C++ program
or not (it is currently open core issue 115 in the ISO C++ committee).
What the above patch does is to issue error on it.
