A JNI method receives incorrect data after the JNI stub gets compiled by C2 compiler

Occurrence of the bug:
-----------------------
1. the bug is known to occure with the -server option on Win32
2. The bug seem to be dependent on the PC. The bug only occured after having taken
   a larger data file on a Tecra 9100
3.) The bug could not be reproduced on the Tecra by using -client
4.) The bug disappears when the following method
    gets exluded
        exclude com/sap/mw/rfc/engine/Compress CsRCompress

The customers provides a test case in the attachement.
Please follow the readme.txt file.

General architecture:
1. Customers uses a native program called jlaunch to start the Java VM
   jlaunch has already all native libs compiled into it.
2.) Java application read a data stream
3.) Java application passes data stream to native method for compression
4.) Native function corrupts data whenever the JNI function gets compiled
5.) Test application reads and writes a datastream into it's own compression library until it crashes.
