Hi Jason,

Could you try to run weechat without plugins, with: weechat -p
Does it crash too?

If not, maybe one plugin is causing the problem. So you can start without
plugins and try to load them one by one (/plugin load <tab>).

If you still have crash with the -p argument, then try:

  weechat -p --no-gnutls --no-gcrypt

These 2 debug parameters will disable gnutls and gcrypt (they must not be used
in a normal run). Maybe the init of these libs is crashing.

And could you please get a backtrace of the problem by running weechat in gdb?
Look at user's guide for more info:
http://weechat.org/files/doc/devel/weechat_user.en.html#report_crashes

If you need more help, please join #weechat on irc.freenode.net, there are lot
of people (including me) to help you.

Cordialement / Best regards.
