/* This test triggers a crash when a physname for a subprogram has
a method pointer to an anonymous struct as a parameter. This
situation is possible with templates and lambda expressions,
reproduced here by the following source code:
class a
{
public:
int doit (void) { return 0; }
};
class crash
{
public:
crash (int (a::*mp) (void)) {}
};
In order to avoid lambdas, the resulting output has been edited to
remove the DW_AT_name attribute from the DIEs describing "class a." */
