Hi, While debugging an instance of this bug I noticed that plperlu always removes the SIGFPE handler and sets it to ignore:
andres@awork2:~$ psql -p 5435 -U postgres -h /var/run/postgresql test Timing is on. psql (9.1devel, server 9.1.5) Type "help" for help. test=# SELECT pg_backend_pid(); pg_backend_pid ---------------- 9287 root@awork2:/home/andres# grep -E '^Sig(Cgt|Ign)' /proc/9287/status|awk '{print $2}' 0000000001301800 0000000180006287 test=# DO LANGUAGE plperlu $$$$; root@awork2:/home/andres# grep -E '^Sig(Cgt|Ign)' /proc/9287/status|awk '{print $2}' 0000000001301880 0000000180006207 Note the 8'th bit being unset in SigCgt and set in SigIgn. Thats SIGFPE... Not sure how relevant this really is, but it could cause errors to be ignored...
