Subject: BUG #17095: ./configure fails thread_test.c when run under TSAN
Date: Thu, 08 Jul 2021 20:01:21 +0000
Message-ID: <17095-374e65bfa8737607@postgresql.org> (raw)
The following bug has been logged on the website:
Bug reference: 17095
Logged by: Vitali Lovich
Email address: vlovich+github@gmail.com
PostgreSQL version: 14beta2
Operating system: Arch Linux
Description:
When I run configure with -fsanitize=address (using clang 13 at revision
d3676d4b666ead794fc58bbc7e07aa406dcf487a), it errors out because
`thread_test.c` is violating thread safety.
Specifically it complains about the access of errno2_set, errno1_set,
thread1_done, & thread2_done being read/modified from multiple threads
without any kind of synchronization. AFAICT these TSAN errors are correct.
