c++ - Bug? Member Template Support

reply Anand Krishnamoorthi <anand.shankar.k gmail.com> writes:
Hi,

Here's an obscure bug.

My understanding is that the code
is Standard C++.

I get

Internal error: exp2 1229

when a member function ptr is
passed as a non type template
argument to a member template.

However when a member function ptr
is passed as a non type template
argument to a global template function,
things work fine.

Code attached.

Best Regards,
Anand.

You can get the .cpp file as plain text file at the web interface:

I think Digital Mars (or whoever) should fix this problem, its
not the  first time I have seen this problem.
