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.

Thread pointer: 0x0
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

Hi,

Normally, this kind of issue occurs due to disk related problems. These two lines, also indicate that in backtrace.

xtrabackup(os_file_read_func(int, void*, unsigned long, unsigned long)+0x26b) [0x5f4ebb]
xtrabackup(xb_fil_cur_read(xb_fil_cur_t*)+0xef) [0x59dc2f]

Can you check if Hard disk is okay and enough space ? i.e dmesg and df -h
I would also like to check PTDEBUG=1 output of this command. i.e

Shell> PTDEBUG=1 innobackupex --user=root --stream=xbstream --compress --compress-threads=4 ./ > stgBackup.xbstream
