Subject: Re: [4.3 regression] calling a function with undefined parameters
causes segmentation fault at -O1 or higher
Hi,
the patch seems to pass my local testing, but on Zdenek's tester I get
curious results on i686:
Tests that now fail, but worked before:

Those are all timeouts that does not reproduce for me on local testing
(and the tests don't even seem that slow). I am inclined to think that
this is just random noise but will try to check before comitting.
