This is caused by a trick of gc to estimate where the C compiler's
run-time system places the stack.

It's quite possible that gc does not support this unusual processor/OS
combination.  It does support the Linux libcs and I believe it also
knows about PPC processors.  The combination of these two is probably
not anticipated.  Maybe HJ Boehm can tell you what is necessary for
this.

If everything fails, oo2c can be built without gc.  See the chapter
about installation in the reference manual for details, and a
discussion of the disadvantages involved.
