ECO KIT SUMMARY:

A dupatch-based, Early Release Patch kit exists for Tru64 UNIX 5.1 that
contains solutions to the following problem(s):

  User applications that are linked with pthreads abort with an "illegal
  instruction" error upon startup. This problem occurs if the application
  has defined the variable name "table".

  The following command should be used to determine if the user application
  has defined the variable name "table":

> nm <file name of user application executable> | grep table

  The problem occurs in the following libpthread libraries:

                       _________________________________________
                      | Tru64 Version | Pthread Library Version |
                      |---------------|-------------------------|
                      | 5.1 PK5 | 3.18-138 |
                      |---------------|-------------------------|
                      | 5.1A (with no | 3.18-120 |
                      | patchkit) | |
                      |_______________|_________________________|
                      | | |
                      | V5.1A PK1 | 3.18-136 |
                      | | |
                      -------------------------------------------

   To determine the version of the libpthread library, run the following
   command:

> what /usr/shlib/libpthread.so | grep -i decthread
