Services Crash on Authentication #36

Open xnite opened 8 years ago

xnite commented 8 years ago

Sometimes when authenticating to my account (possibly related to /oper at the same time which also autojoins me to channels but via ircd not services) services completely crashes. Tail of strace

Was there a fix for this? I'm running into this issue today.

Could you please try and get a stack dump?

Compile x3 in debug mode, and try and reproduce. The key is that the compiler doesnt use "-O3" to optimize the code beyond easy debugging.

Then run in gdb, or use gdb to open the core file

I need output from "bt full"

Thanks, -Rubin
