I am running SMP 4.0-current as of Oct 18.

I attempted to profile an application, using 'gcc -pg ...'.
Compiling/linking worked OK.  When I attempt to run the application,
it reports a stack overflow.

gschem and libgeda.so.5 were built with 'gcc -pg ...'.

# gschem
ERROR: Stack overflow

When I do this with a smaller application, it works OK.

What can I do to remedy this situation?

I don't understand why the two libc entries.  libc.so is linked to
libc.so.4.  None of the Makefiles calls for libc.so.3, only libc.so.
