RE: Segmentation error during dlclose()

[Ilesh Garish]

Hi Jim,

Here is the sample code, which is not working on Linux.

 <<Native.zip>> 
Please build the require component using shlib.sh file included in the
attachment.

I am trying in following configuration:
1. Red Hat Linux 6.0
2. JDK 1.3.0

I try to use native methods and pthread in the same code. If I remove
pthread reference then it works fine.
Test program is TestPgr.java which will call native method in which I use
pthread calls.

Hope now you can reproduce the problem.

I will appreciate your help.

Thanks,
Ilesh H. Garish
