> Key: ASTERISK-30418
> URL: https://issues.asterisk.org/jira/browse/ASTERISK-30418
> Project: Asterisk
> Issue Type: Bug
> Security Level: None
> Components: Applications/app_confbridge
> Affects Versions: 18.16.0
> Environment: Server has a 6 core Intel CPU with 16 gigs of RAM.
> The OS is OpenSuSE 15.3 and is running Vicidial
> Reporter: Michael Cargile
> Assignee: Michael Cargile
> Severity: Major

> My dev system keeps crashing while running Asterisk 18.16.0. I am in the process of validating our software with Asterisk 18. This time it seems to have seg faulted in the ConfBridge code. It crashed previously with a double free, but sadly I had forgotten to compile with DONT_OPTIMIZE so the dump was useless. Here is the back trace for the Seg Fault:
> {quote}
> Core was generated by `/usr/sbin/asterisk -vvvvvvvvvvvvvvvvvvvvvgcT'.
> Program terminated with signal SIGSEGV, Segmentation fault.
