Hi, I'm working on an Apache Module since few months and it works fine until this morning... I made a little upgrade on a regular expression. All is fine on the machine where I develop but when I deploy Apache on an other machine, I obtain a segmentation fault when I start httpd process...
The old regular expression : #define EXP_REGU "<\\?xml version=\"1\\.0\" encoding=\"UTF-8\"\\?><endbRequest xmlns=\"UdbEndbInterface\" xmlns:xsi=\" http://www\\.w3\\.org/2001/XMLSchema-instance\"; xsi:schemaLocation=\"EndbInterface C:[\\]{1,2}endbRequest\\.xsd\"><Line-Id>(.{0}|[[:alnum:]]{20})</Line-Id><Operator-Code>(.{0}|[0-9]{2})</Operator-Code><Country-Code>(.{0}|[0-9]{2})</Country-Code><Location-Area-Code>(.{0}|[0-9]{5})</Location-Area-Code><Advanced-Location-Info>(.{0}|[[:alnum:]]{10})</Advanced-Location-Info><Calling>([0-9]{9,11})</Calling><Called>([0-9]{2,6})</Called></endbRequest>" The new one : #define EXP_REGU "<\\?xml version=\"1\\.0\" encoding=\"UTF-8\"\\?><endbRequest xmlns=\"UdbEndbInterface\" xmlns:xsi=\" http://www\\.w3\\.org/2001/XMLSchema-instance\"; xsi:schemaLocation=\"EndbInterface C:[\\]{1,2}endbRequest\\.xsd\"><Line-Id>(.{0}|[[:alnum:]]{20})</Line-Id><Operator-Code>(.{0}|[0-9]{2})</Operator-Code><Country-Code>(.{0}|[0-9]{2})</Country-Code><Location-Area-Code>(.{0}|[0-9]{5})</Location-Area-Code><Advanced-Location-Info>(.{0}|[[:alnum:]]{10})</Advanced-Location-Info><Calling>([0-9]{9,11})</Calling><Called>([0-9]{2, 8})</Called></endbRequest>" I try to run httpd process with gdb to identify why Apache die in Segmentation Fault but I didn't really succeed... This is the gdb traces (I put a breakpoint after my last called method and next, I ran step by step) and the error seams to be in the Apache Core... ---------------------------------------------------------------------------------------------------------- [EMAIL PROTECTED] bin]$ gdb httpd GNU gdb Red Hat Linux (6.3.0.0-1.62rh) Copyright 2004 Free Software Foundation, Inc.
