Can't see anything relevant changed recently...
I can see that findFun gives an error if the function is not found,
which I presume is what you call a "crash". However, your workaround
wouldn't catch the situation where a variable exists, but none of the
versions in the search path are functions.
I think you want to use findVar1() instead.
