Hello, gcc - world;

is there a way to initialize variables allocated on the stack to
signalling NaN's on those architectures which support them?

The reason I'm asking is that I have some FORTRAN code which I
want to use on my Linux box using f2c.  The code does depend
on keeping values between subroutine calls (which is non - standard,
but common in old programs), and I'd rather find this out by
having the program die on me once for each variable than by
getting subtly wrong results all the time.

If there is no way, I' selfishly suggest adding this to gcc as a
debugging help (maybe to the malloc - call as well).

Happy hacking
