abort() in vm-engine.c

[Andreas Rottmann]

Hi!

I encountered an "abort()" during compilation of my code.  Bisecting
Guile seems to indicate that the commit responsible is
9b709b0fe1... Here is a backtrace from GDB; note the innermost
stackframe seems suspicious -- the arguments to `vm_regular_engine'
certainly don't look normal:

(gdb) run -x .guile.sls -x .sls -c '(use-modules (spells test-runner))'
Starting program: /home/rotty/.system/bin/guile -x .guile.sls -x .sls -c

;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0
;;;       or pass the --no-auto-compile argument to disable.

Unfortunatly, I have no idea what this is triggered by and hence can not
provide a small testcase.  If needed, I can provide a tarball containing
the code that is needed to reproduce it.
