HI

Issue :
crash while using regex
/^((?!hub|data_engine|nads_|heartbeat_engine2|queuemon|request_monitoring|critical_component_monitor|weblogic).)*$/

also with /^((?!ext4).)*$/

we are using pcre_exec.c[] in our app for matching processes but while using
regex as mention above our app is crashing .
