Description Volker Reichelt 2007-12-08 20:38:10 UTC 
The C++ frontend issues a broken diagnostic for the following invalid
testcase since GCC 3.1:

==============================
extern double fabs(double);

void foo(double x)
{
  fabs(x)();
}
==============================

bug.cc: In function 'void foo(double)':
bug.cc:5: error: '#'abs_expr' not supported by dump_expr#<expression error>' cannot be used as a function
