As anticipated to Tone, I was finally able to solve the problem.

It looks like somewhere in the code there is a double free or double alloc. It should not be a fatal problem in itself, but cause the program to be aborted if the environment variable MALLOC_CHECK_ (with a trailing underscore) is set to "2" or "3".

An easy workaround is to unset the variable, or to set it to "0" or "1", further info can be found in the malloc man page.
Just add the following line at the beginning of $XCRYSDEN_TOPDIR/xcrysden to fix it forever:

cheers, and thanks to Tone for the support
