Description:
Segmentation fault in fill_record for multi_update for bitmap field. This is seen in wl7159 and other related wls(8003,7828). However it does not look related to wls implementation. tried reproducing on trunk but could not but its a multithreaded bug and difficult to conclude anything on this.
