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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.

key_buffer_size=8388608
read_buffer_size=131072
max_used_connections=0
max_threads=500
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 = 206883 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Hello @CompWebStudio, The link provided in the previous post is a good place to start when troubleshooting InnoDB corruption. As far as why this happened after the update to version 78, can you share the contents of the /etc/my.cnf file on this system? EX: cat /etc/my.cnf
Thank you.
