Matt Jordan commented on ASTERISK-22763:
----------------------------------------

It looks like your backtrace is still from binaries that don't have debug symbols:

{noformat}
#0  0x00000000004455c2 in __ao2_find ()
No symbol table info available.
#1  0x00000000004bc2be in find_interface ()
No symbol table info available.
#2  0x00000000004bc419 in ast_format_cmp ()
No symbol table info available.
#3  0x00000000004c0262 in cmp_cb ()
No symbol table info available.
#4  0x0000000000444a5d in internal_ao2_callback ()
No symbol table info available.
#5  0x0000000000445091 in __ao2_callback ()
No symbol table info available.
{noformat}

Unfortunately, that means we don't really know much about what occurred leading up to the crash.

Can you reproduce the crash? What was the system doing leading up to it? Can you produce a backtrace with all of the symbols?
