The first PLT internals question I expect to look into is whether, in

Yes. It looks like evaluation is four `require's deep (not counting the original
module). By looking at `menv->module->name' in frame 353, you might be able to
tell which module is being run.
Scheme_Object 0x7fff2f7adc30 type=147 Scheme_Object 0x7fff2f7c8580
type=45 scheme_unix_path_type $5 = 0x7fff2f7bbd40
"/usr/local/plt-4.2.5/lib/plt/collects/srfi/14/char-set.ss"
During loading of that module is not an unlikely time for
"integer_to_char" to be called, too.
That's a disappointingly innocuous-looking module. And, from what I've
found so far, the dependency graph on that module doesn't directly
implicate a less-innocuous module.
I have another question: At some point, the Scheme application code does
an "eval" of a file, and that file has "require"s, which likely pull in
that SRFI-14 module indirectly (just like the code that does the
"eval"). Can you tell from the stack trace whether or not we are
evaluating such an "eval"?
