The Valgrind documentation says --smc-check=all should fix this, but it 
doesn't.

Ubuntu has a 6.0.2 package that builds in Debian, but it still has this 
bug.  (Same stacktrace as 6.0.1 under gdb; once a different one (below) 
under valgrind --smc-check=all --error-limit=no 
--log-file=scilab_valgrind%n .)

A fatal error has been detected by Scilab.
Please check your user-defined functions (or external module ones) 
should they appear in the stack trace.
Otherwise you can report a bug on http://bugzilla.scilab.org/ with:
  * a sample code which reproduces the issue
  * the result of [a, b] = getdebuginfo()
