Current process (0x4f430638) infected with signal 11 (SIGSEGV)
Address 0x0x0000000000e992c2 (ssql(bool, float, float, long double,...)(...) __restrict+0x3d), siginfo (code, address) = (1, 0x0x0000000000000004)

- Followed by a stack trace that includes modules:
ssql__rmplans
ssql_save_SQL
sqt_put_in_stmtcache
Note: A sample of a complete stack trace is available under Attachments.
- These may be followed by further "infected with signal 11" error in the module ssql_droptext() that can crash ASE:
Current process (0x1bc33a4a) infected with signal 11 (SIGSEGV)
Address 0x0x0000000000e93233 (ssql_droptext+0x970), siginfo (code, address) = (1, 0x0x0000000000000082)
- Showing stack trace including modules:
ssql_droptext
ssql_purge_stmt_hastemp
clean_process
- As this process is holding SSQLCACHE_SPIN, ASE will go down showing log entries including:
Spinlocks held by kpid 12345678
