you have no symnbols. no gdb debug. i see 3 crashes in that log. (chrashdump
keeps being appended to each crash):

each different. the first 2 i assume are crashes in libc - probably due to
passing in a bad ptr to a str func or a malloc related bug (double-free. free
junk pointer etc.). the last - who knows. access of some incorrect pointer.

you have no debug info to use to do anything. i suggest you read up on asan
(see enlightenment.org/contrib/efl-debug ) and rebuild efl and e with asan
support (and gdb debug of course) then submit the asan logs (from
~/.e-log.log). arch linux has efl-git-asan and enlightenment-git-asan aur
packages just for this purpose. you can read their PKGBUILD files to see how
efl and e are built with asan.

https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=enlightenment-git-asan

(PKGBUILD files are literally shell scripts pretty much...).
