Not the same as http://bugs.mysql.com/bug.php?id=42052 mysql-5.1-telco-6.4 revno: 3224 Running a 2-dn configuration with a mix of ndbd and ndbmt I received a Program terminated with signal 11, Segmentation fault.

duplicate of http://bugs.mysql.com/bug.php?id=42254 100% sure, however, that hasnt been retested (to my knowledge) except by me so keep this open, and close it as duplicate once retested

Description: Hi, Was running im mixed mode where one node was a ndbd and the other was a ndbmtd.
