>   Bug #57274 SET GLOBAL debug crashes on Solaris in embedded server mode
>              (variables_debug fails)
>   
>   The problem was that "SET GLOBAL debug" could cause a crash on Solaris.
>   The crash happened if the server failed to open the trace file given in 
>   the "SET GLOBAL debug" statement. This caused an error message to be
>   printed to stderr containing the process name. However, printing to
>   stderr crashed the server since the pointer to the process name had
>   not been initialized.
>   
>   This patch fixes the problem by initializing the process name 
>   properly when doing "SET GLOBAL debug".
>   
>   No test case added as this bug was repeatable with existing test
>   coverage in variables_debug.test.
