Segmentation fault after new wine update and install

[Juraj Hercek]

Hello,

I've updated today from wine and got into troubles after installing it - 
got Segmentation fault. I dig in it and figured the problem is my 
environment variable WINEDLLPATH which was set to "." (current 
directory). The back trace of stack during the crash was similar to this 
(just the frames 5,6,7,8 were repeating many times - until stack overflow):

So, I guess wine pthread functions table should be initialized before 
any (system) library get's chance to throw error, otherwise we have SIGSEGV.

I've fixed the error on my side with 
WINEDLLPATH="/usr/local/lib/wine:.". Anyways I think it's a workaround 
not a solution... Since I don't know much about initialization, I would 
leave the real fix for someone more skillful.
