[Chicken-users] Segfault when trying to embed Scheme code

Hi, I got segfaults trying to make C code call Scheme functions (as described in the Wiki -- I actually copied and pasted the scm and C examples there). But I'm using Chicken version 4.2.2 - SVN rev. 1622. Is it OK to report this as a possible problem in the current SVN version, or should I try

[Chicken-users] Was crunch really discontinued? Is there an alternative?

Hello! I've been looking for some Scheme implementation that is suitable for number crunching and also supports SRFIs like 42 (eager comprehension), 45 (laziness), 25 (multidimensional arrays), and some others. So, I have tested Chicken, Bigloo and Gambit. There seems to be a necessary trade-off
