Looks like chamelium api rpc call crashes, regardless of what causes this - that is a clear bug in IGT/Chamelium api.

Comment 4 emersion 2019-10-11 08:20:31 UTC
These xmlrpc_server_info_disallow_auth_ntlm calls in the stack trace look erroneous, since this function only contains a single instruction (setting a structure field to a given value). We're probably missing debug information for xmlrpc-c, so we can't trust the stack trace inside the lib anyway.

The fact that we get SIGQUIT is weird. The lib contains a bunch of abort() calls which may be called from xmlrpc_client_call2, however abort() triggers SIGABRT, not SIGQUIT. I have no clue why this happens atm.

In any case, this is a bug in IGT as Stan said.
