[asterisk-bugs] [JIRA] (ASTERISK-27094) res_fax: Deadlock when using Local channels and fax gateway

[David Brillert (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-27094?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=243428#comment-243428 ] 

David Brillert commented on ASTERISK-27094:
-------------------------------------------

I don't understand why the backtraces are still missing symbols
Asterisk was compiled with:
DEBUG_THREADS, DONT_OPTIMIZE and BETTER_BACKTRACES
But not MALLOC_DEBUG

What flag could be missing?
I'll try recompiling and will reproduce. Which backtrace file should I be looking at and which text would tell me if my backtrace is useful before I upload it to the bug report?
