This is a regression from 2.95. Currently, we get the following on mainline
and 3.3:
pr7939.cpp:2: error: `<anonymous>' has incomplete type
pr7939.cpp:2: error: invalid use of `void'
pr7939.cpp:2: error: partial specialization `foo<T, void>' of function
template
pr7939.cpp:2: internal compiler error: in comptypes, at cp/typeck.c:913
Please submit a full bug report,
while we used to get this on 2.95:
pr7939.cpp:2: template-id `foo<T, void>' in declaration of primary template
So, there is actually an improvement on the error message (the parser is
able to understand that the code is trying to define a partial
specialization of a function template, which is indeed a great diagnostic),
but then it ICEs during error recovery. I think the error message could also
be a little epurated (removing those other lines if possible, especially the
one with <anonymous> which is really cryptic), and maybe specifying
explicitally that "partial specialization of function template is not
allowed by ISO C++".
