| Subject: | Bottomless Recursion and Segmentation Fault under Perl 5.10.0 |
Dear John Clutterbuck,
Hi. This is imacat from Taiwan. I found that your
Devel-ObjectTracker-0.4 gets into bottomless deep recursion under Perl
5.10.0, which eats up all the memory and dies. I tried to investigate
further. It seems that in package DB of your ObjectTracker.pm, the "sub
sub" calls itself recursively, which in turn goes infinitely.
I do not know what to do with this situation. Maybe you can take
some time to look into this issue.
The terminal log is attached below. Hope that this helps. Please
tell me if you need any more information, or if I could be of any help.
Thank you.
