Problem to gdb on chromium android

[Jincheol Jo]

Hi. Chromium team

I am facing a problem to gdb on chromium android M102.

Thread 1 "d_webview.shell" hit Breakpoint 2, content::WebContentsImpl::UpdateFaviconURL ()
    at ../../content/browser/web_contents/web_contents_impl.cc:6457
6457      observers_.NotifyObservers(&WebContentsObserver::DidUpdateFaviconURL, source,
(gdb) bt
Python Exception <class 'gdb.error'> Call Frame Instruction op 45 in vendor extension space is not handled on this architecture.:
#0  content::WebContentsImpl::UpdateFaviconURL () at ../../content/browser/web_contents/web_contents_impl.cc:6457
Call Frame Instruction op 45 in vendor extension space is not handled on this architecture.
(gdb)

Gdb is working but "bt" command is not working.

Plz let me know if you have any idea.

Thanks.
