Description Volker Reichelt 2011-11-30 21:29:51 UTC 
Trunk produces a broken diagnostic for the following code snippet:

========================================
template<typename T> void foo(T, T);

void bar(void* p)
{
  foo(0,p);
}
========================================

bug.cc: In function 'void bar(void*)':
bug.cc:5:10: error: no matching function for call to 'foo(int, void*&)'
bug.cc:5:10: note: candidate is:
bug.cc:1:27: note: template<class T> void foo(T, T)
bug.cc:1:27: note:   template argument deduction/substitution failed:
bug.cc:5:10: note:   conflicting deductions for parameter 'T' ('int' and '#'pointer_type' not supported by dump_expr#<expression error>')

Mine, this is caused by PR51230, for sure.
