: With what parameter?
: __builtin_return_address(0) should always work

the parameter was "3". I now tried to first call __builtin_frame_address()
and when that returns 0 to reduce the parameter. But then 
__builtin_frame_address crashes.


: With non-zero parameter, the work __builtin_return_address()

: that you should abandon all hope.

But it seems to work without optimization; and without problems on an Intel
processor and on Suns. I need it to store the program counter at the time
when a piece of memory is allocated for reporting later on memory leaks and
their origin in my memory manager.

Is there another reliable way to access the program counter?
