TROUBLESHOOT: ERRO PARA INICIAR MYSQLD (Error: trying to access a stray pointer)

Um dia tive problema para iniciar o mysqld no centos6.9 obtendo o erro abaixo.
Resolvi renomeando para old os arquivos ibdat_1 e ib_logfile0 que se encontram na pasta /var/lib/mysql e tentando iniciar novamente o serviço.

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. 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.

key_buffer_size=8384512
read_buffer_size=131072
max_used_connections=0
max_threads=151
thread_count=0
connection_count=0
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 338336 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

where mysqld died. If you see no messages after this, something went
terribly wrong...
