One thing to be aware of is that the so-called "portable"
implementation of alloca() in alloca.c just doesn't work with Guile,
because it doesn't really allocate memory on the stack.
In fact, alloca.c was removed for this reason in 2004:
2004-09-08 Marius Vollmer <[EMAIL PROTECTED]>
* Makefile.am (EXTRA_libguile_la_SOURCES): Removed "alloca.c".
Does anyone know what caused it to reappear? ChangeLog doesn't reveal
anything.
Guile fundamentally requires a real alloca, which means it has to be a
compiler builtin.
