Is your system short of memory? I can't imagine how this assertion can be triggered except if out of memory.
It may be problem with memory because we have ulimit -v 8388608 in start scripts to avoid server crash due to another bug https://issues.apache.org/bugzilla/show_bug.cgi?id=53290 This segfault may be related to that bug when apache start using all memory reserverd for it Piotr
It is normal and intended behavior for 2.2 to segfault if memory allocation fails. This won't be changed. 2.4 should abort with a logged error message if out of memory. r1343109 adds the error handling for this particular code path (compiling a regular expression).
Please help us to refine our list of open and current defects; this is a mass update of old and inactive Bugzilla reports which reflect user error, already resolved defects, and still-existing defects in httpd. As repeatedly announced, the Apache HTTP Server Project has discontinued all development and patch review of the 2.2.x series of releases. The final release 2.2.34 was published in July 2017, and no further evaluation of bug reports or security risks will be considered or published for 2.2.x releases. All reports older than 2.4.x have been updated to status RESOLVED/LATER; no further action is expected unless the report still applies to a current version of httpd. If your report represented a question or confusion about how to use an httpd feature, an unexpected server behavior, problems building or installing httpd, or working with an external component (a third party module, browser etc.) we ask you to start by bringing your question to the User Support and Discussion mailing list, see [https://httpd.apache.org/lists.html#http-users] for details. Include a link to this Bugzilla report for completeness with your question. If your report was clearly a defect in httpd or a feature request, we ask that you retest using a modern httpd release (2.4.33 or later) released in the past year. If it can be reproduced, please reopen this bug and change the Version field above to the httpd version you have reconfirmed with. Your help in identifying defects or enhancements still applicable to the current httpd server software release is greatly appreciated.
