Resolving template functions through ?
Last modified: 2007-03-26 23:47:42 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.
Created attachment 26353 [details] funcptr2.cc code
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.
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.
