Scheme_Object 0x7fff2f7adc30 type=147  Scheme_Object 0x7fff2f7c8580 
type=45 scheme_unix_path_type $5 = 0x7fff2f7bbd40 

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"?
