commit bc6b36682f188020ee4770fae1d41bde5b2c97bb
Author: Andrew G. Morgan <morgan@kernel.org>
Date: Wed May 3 19:18:36 2023 -0700
Correct the check of pthread_create()'s return value.
This function returns a positive number (errno) on error, so the code
wasn't previously freeing some memory in this situation.

Credit for finding this bug in libpsx goes to David Gstir of
X41 D-Sec GmbH (https://x41-dsec.de/) who performed a security
audit of the libcap source code in April of 2023. The audit
was sponsored by the Open Source Technology Improvement Fund
