Core dump on `ntatag_ua` #229

Closed vsedyshev-intermedia closed 3 months ago

vsedyshev-intermedia commented 9 months ago

Could you please suggest me where root cause of issue? I create nta->agent and start legs with calls ... Some time receive core dump with next stacktrace:

(gdb) bt

When I disable NTATAG_UA(1) on agent I receive next one traceback:

(gdb) bt
#0  0x000055555555ec40 in ntatag_stateless ()

Look like agent pass NTATAG_STATELESS(1) in agent creation tags and it lead to this tracebacks... Since NTA start wortking with STATELESS mode I assume that calling stateful lead to error result instead coredump...
