The file that uses the spinlocks:
/src/backend/storage/lmgr/s_lock.c
can be compiled standalone with -DS_LOCK_TEST
To get the test to compile I had to link in tas.o as the attached patch
shows. Unfortunately this doesn't work for platforms that don't have a
tas.o, bailing out with file not found. Perhaps it's not important to fix
this test, but I thought I'd mention it.
Anyway the test exits with
Stuck spinlock (80618e9) detected at ./s_lock.c:355.
on a linux gcc build this exits with
Stuck spinlock (0x5013ad) detected at ./s_lock.c:402.
