| Subject: | Bottomless Recursion and Out of Memory |
Dear Scott Penrose,
Hi. This is imacat from Taiwan. I found that your
Attribute-Persistent-1.1 gets into bottomless deep recursion when
loaded, which eats up all the memory and dies. I tried to investigate
further. I tried to investigate further. It seems that, in the package
UNIVERSAL or your Persistent.pm, the "use AnyDBM_File;" get itself into
this trouble.
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.
