By chance are you using an x86 machine, gcc 2.95.2, and the sgc.c
distributed with MzScheme version 103?

If so, the problem is a bug in gcc's optimizer. The current sgc.c in
CVS has been modified to avoid the problem. (I can send you the new
file by e-mail if you need it.) Another way around the problem is to
turn of optimization when compiling sgc.c.
