[plt-scheme] Core dump using SSL

Hi,

We're getting a repeatable seg fault after about a day of
uptime:

  Seg fault (internal error) at 0x12

We're pretty sure it is in the SSL bindings.  We have a
700MB core dump, a slightly smaller but still enormous gdb
backtrace, and the following output from gdb mzscheme core:

Core was generated by `mzscheme -qjr run-sbcs.ss'.

To those who might fix this:

Let us know what we can do to help fix this problem.  We
can, for example, give you access to the machine that has
the core file.

Thanks,
Noel
