int defValue() { return(0); }
int(*defaultValue)() = defValue;

void a(int blah = defaultValue()) {}

int main() { a(); }


/*
$ g++ a.cpp -o a
a.cpp: In function `int main()':
a.cpp:20: internal compiler error: Segmentation fault

If I drop the indirection, like this:

void a(int blah = defValue()) {}

..it compiles.

This might be slightly off topic, but here's what I originally tried to do:

Confirmed.  I think this is valid code, ICC 6.0 accepts it in strict mode.
pr15759.cc: In function `int main()':
pr15759.cc:6: internal compiler error: tree check: expected class 'E', have 'd' (var_decl) in bot_manip, at 
cp/tree.c:1227

The code is indeed valid. It fails since at least 2.95.

[Bug c++/15759] ICE with function pointers

[pinskia at gcc dot gnu dot org]

------- Additional Comments From pinskia at gcc dot gnu dot org  2005-01-29 13:43 -------
Note the following is make sure that we create correct code:
extern "C" void exit (int);
extern "C" void abort();
int defValue() { exit(0);return(0); }
int(*defaultValue)() = defValue;
void a(int blah = defaultValue()) {}
int main() { a(); abort (); }

And with checking not enabled we get the correct code (which I find werid but hey).
