Situation

Free detected a corrupt trailing redzone Abend in eDir 8.8.1 or eDir 8.8.1 FTF2

Pagefault abends in ds code.

Resolution

The code stacks appeared to be random, until we enabled the SET ALLOC MEMORY CHECK FLAG =ON setting and gathered another core dump. See stack below.

This abend is resolved in eDirectory 8.8.2 or greater.
