[Gimp-user] Perl-fu script crashes *Except* under debugger

[Jeff Trefftzs <trefftzs@tcsn.net>]

Hi all -

I have spent most of the last three days hacking at a perl-fu 
script to place copies of a selection along a path, with and 
without rotation and scaling.  When I run it under the perl 
debugger it works fine; when I try to run it directly from 
either the perl server or from the menu in Gimp, it segfaults.

Well, mostly it segfaults.  For a while it was working just 
fine, but during a Gimp session this evening it suddenly started 
segfaulting again, sort of in mid-career.  I think the problem 
lies in the use of an eval construct to catch the error when 
gimp_path_get_point_at_dist is given a dist that is beyond the 
end of the path.  I use this construct because I couldn't find 
anything else that would give the length of a path, so I do a 
sort of binary search to find the end, depending on the eval to 
catch the error.

Details:  Gimp 1.2.2, perl-5.6.0
