[Bug c++/36776] New: Internal compiler error with template/pointer to member functions

["maksverver at geocities dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I first encountered this problem with GCC 4.3.1. With that compiler, the
program compiles fine (without warnings) but crashes at runtime. I tried a
recent snapshot of version 4.4 before submitting a bug report, and there an
internal compiler error is produced instead. So although this bug report is
filed for 4.4, a similar bug is present in at least 4.3.1 (and probably
others).

I don't really understand what causes the bug, so I'll just give you the source
code for a (self-contained, simplified) test case that causes the internal
compiler error along with my output, and hope you are able to figure it out.
;-)
