Hi Érico, all,

Replying to my own mail as I wasn't subscribed to this list and missed
your mail. I am subscribed now.

Thanks for your reply! I applied your patch and compiled freeswitch with
"-g3". Then I got this in the backtrace:

"0x7ffeb39abac0s": not in executable format: file format not recognized

Continuing.

I hope the "optimized out" items aren't too much of an issue. Would be great if you could take a look.

Thanks!
