munmap_chunk(): invalid pointer after pacman -Syu

Greetings,

After an otherwise apparently successful

pacman -Syu | tee ~HOME/Documents/pacman-2018-06-22.txt

I got

munmap_chunk(): invalid pointer

. Pacman log is:

I don't know which program spit out that error or if it is significant at all. The error was on a line by itself with no other text or references. Here is the tee:

and it was right below the 3/3 line where it appeared. A Pacman error? Google results seem to imply a c error within a program but in the search results I found this error usually indicated which program was spitting out the error. Any pointers on how to trouble shoot this?  Or if I have to at all - so far everything otherwise seems to behaving as expected?

Re: munmap_chunk(): invalid pointer after pacman -Syu

This is an error appearing right after a pacman hook is being run. You could check the hook files in the referenced directory, until you find the message text in /usr/share/libalpm/hooks/update-desktop-database.hook

This hook runs the update-desktop-database command -- does it error out if you run it again?

Re: munmap_chunk(): invalid pointer after pacman -Syu

Thank you for the hooks pointer. Running another pacman -Syu did not produce the error message, but the update-desktop-database hook was not called this time, so perhaps I will have to wait until a package is updated which triggers this hook to see if the error is repeated(?).
