A couple of ideas:

  1. What `CFLAGS' are you using?  In particular, are optimizations
     enabled?

     With GCC, compiling without optimizations usually yields a Guile
     that stack-overflows because the evaluator would use so much stack
     space that the default stack limit is quickly hit.  You could have
     the same problem with IBM's xlc, so make sure to enable
     optimizations.

     Actually, `configure' only adds `-O2' when GCC is being used, so
     I'm pretty sure it's up to you to pass `configure' or `make' the
     right CFLAGS, e.g.,

       CFLAGS="-the-option-that-enables-optimizations" ./configure

     If that fixes the problem, then we can change `configure' to use,
     e.g., `AX_COMPILER_VENDOR' [0] to automatically add optimization
     options that correspond to the compiler being used.

  2. Is it a 64-bit platform?

     If so, it may be the case that the default stack limit (see
     `debug-options') is about two times smaller than what you need.

Thanks,
Ludovic.
