LP #1540296: Getting error while taking percona incremental backup

Description

**Reported in Launchpad by santhosh last update 10-04-2016 04:17:23

Getting the below error
2016-02-01 10:21:53 7fde8e398700 InnoDB: Assertion failure in thread 140593845602048 in file ut0mem.cc line 105
InnoDB: Failing assertion: ret || !assert_on_error
InnoDB: We intentionally generate a memory trap.
InnoDB: Submit a detailed bug report to http://bugs.mysql.com.
InnoDB: If you get repeated assertion failures or crashes, even
InnoDB: immediately after the mysqld startup, there may be
InnoDB: corruption in the InnoDB tablespace. Please refer to
InnoDB: http://dev.mysql.com/doc/refman/5.6/en/forcing-innodb-recovery.html
InnoDB: about forcing recovery.
10:21:54 UTC - xtrabackup got signal 6 ;
This could be because you hit a bug or data is corrupted.
This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

This issue is due to malloc only when I tried with 4G of RAM there was no issue,
Thanks percona support team.
Pls close this incident

I am able to take core dump , my script for taking full backup works fine , only in incremental backup i am facing this.
Let me try with 4G RAM and check if its related to malloc.
