Hi Mathieu,

 

Is it possible to send me reproducible test case for this?  The crash is related to cleanup 
of memory structures used to access tied hashes, so maybe you could look for any use of tied
 hashes in your application, and then write a simple program using the same tied hash module
, and see if it crashes too?

 

Iâ??m also interested to know if the crash would go away if you used ActivePerl 820 for buil
ding the application.

 

Cheers,

-Jan

Subject: [PDK-Beta] stack trace using pdk 7

 

Using pdk (from this file PDK-Pro-6.9.92.275147-linux.tar.gz), I have an executable that die
s with a stack trace (see below). The executable was built on Fedora Core 3 with ActivePerl 
813.

The problem execution happened on an install of Fedore Core 4 with no activeperl installed. 

Any idea as of why this would happen?

I have to admit we were happily using PDK 5.3 until we need to use encoding "UTF-8", which d
oesn't work with the older PDK for some reason.
