Sure, this is a ss20 (sun4m), i.e., 32-bit.

I downloaded the test and gave it a go, seg fault.

Here's the log of make test:

This appears to be a SPARC running LINUX
Stack appears to grow down, which is the default.
A good guess for STACKBOTTOM on this machine is 0xeffff000.
Note that this may vary between machines of ostensibly
the same architecture (e.g. Sun 3/50s and 3/80s).
On many machines the value is not fixed.
A good guess for ALIGNMENT on this machine is 4.
Generic mark_regs code may work
./gctest
make: *** [KandRtest] Segmentation fault

and a stack trace in gdb gives us this:
