Currently there are two issues:

- The C stack limit which exists by default might be too large. This
limit is imposed when the operating system limit is RLIM_INFINITY.

- The Boehm-Weiser garbage collector does not always cooperate with
ECL. I have skimmed the code and, at least in theory, it seems that
ECL's signal handler for SIGSEGV is saved by the garbage collector and
called when it finds a SIGSEGV which is not related to the memory
handled by the garbage collector.

The combination of both problems might be what you experience. In
particular, regarding the second problem, I have only seen it when ECL
is built against precompiled versions of the library on Linux and
using the generational garbage collector.
