Keystore format segmentation fault for 33+ threads

My setup is Ubuntu 26.4 + 2 x Intel(R) Xeon(R) 6787P
I see segmentation fault in keystore format self test when number of threads is greater than 32.
Up to 32 self test works as expected.

OMP_NUM_THREADS=33 ./john -test -format=keystore
Will run 33 OpenMP threads

Let me know if anything more is needed.

Reproduce the failure with OMP_NUM_THREADS=32 and 33 using the keystore format self test. Inspect keystore_fmt_plug.c at getPreKeyedHash (line 181) and crypt_all (line 480), using the supplied GDB backtrace as the starting point. Done means the 33-thread self test completes without a segmentation fault while the 32-thread behavior remains working.
