APAR Error Description / Circumvention

-----------------------------------------------
When listing the contents of a directory in service of a client
request, IBM i NetServer exceeded the boundaries of a stack
allocation.  Corruption of the stack frame resulted in abnormal
termination of the system with SRCB6000302.

The terminating call stack contained the following modules:

ISF=D7B8BD3193FFCDE0 NIA=FFFFFFFFC90744E4 module
sl_strings+0x1F74
ISF=D7B8BD3193FFCEA0 NIA=FFFFFFFFC9074530 module
sl_strings+0x1FC0
ISF=D7B8BD3193FFCF60 NIA=FFFFFFFFC5703C54 module
zlsNTFinfo+0x9B4
ISF=D7B8BD3193FFD000 NIA=FFFFFFFFC57039F8 module
zlsNTFinfo+0x758
ISF=D7B8BD3193FFD060 NIA=FFFFFFFFC7C9B348 module
zlsSearch+0x14D8

CORRECTION FOR APAR MA43839 :

allocation prior to copying the data.  The PTF corrects the
problem.
