[Gluster-devel] client crash with AFR in latest tla build

[Mickey Mazarick]

I'm getting the following error with the latest TLA build:

---------
got signal (11), printing backtrace
---------

I thought the modified fuse version might have messed up my afr volume 
but I tried using the tla ver glusterfs--mainline--2.6 and it worked 
like a charm. The non TLA ver also works as well.

gdb gives me:
