[Gluster-devel] undefined symbol in booster / crash with io-cache

[Anand Avati]

Sascha,
 I am a bit confused. Are the 'undefined symbol' from booster and the
segfault associated with each other? (as in, happen at the same time
together?). The undefined symbol most likely looks to be because of a stale
binary of a previous installation lurking around.. can you confirm?

thanks,
avati
