can you get a bt?

v6 commented 9 years ago

// , Whether or not I can get a "bt" depends on what a "bt" is, of course. I can try, though.

v6 commented 9 years ago

// ,

NVM, figured it out.

I'll run it similarly to this until I get another segfault: https://github.com/notsecure/uTox/issues/936#issuecomment-87349335

cebe commented 9 years ago

I'll run it similarly to this until I get another segfault: #936 (comment)

then please paste the output of bt you get from gdb.

GrayHatter commented 9 years ago

if you could start it with gdb and then make it crash, then type bt into gdb, and post the output to a gist... that would be SUPER awesome...

henriqueleng commented 9 years ago

The same here, I noticed it happens when I send big images, the select square also bug. I'm on OpenBSD, running on commit d16f53912b161893431fd16025af94d4d8a14f53 There is a bt: FileTransfer: Starting outgoing image to friend 1. FileTransfer: Friend (1) has resumed file (1) Friend Typing (1): 0 Friend Typing (1): 1

maybe its not compiled with -debug

henriqueleng commented 9 years ago

So it is a toxcore problem? Wondering if any of these lasts commits solves: https://github.com/irungentoo/toxcore/commits/master

henriqueleng commented 9 years ago

Probably solved with last toxcore, @v6 test it

v6 commented 8 years ago

// , @henriqueleng, I just tested it. I can confirm that this bug was fixed with the latest toxcore. However, I'm curious what could have caused this bug.
