Now the debug log is a bit more chatty, but the error remains:

Dovecot forks a child process to execute the program. Subsequently, at
some point, the child process fails with a segmentation fault. Granted,
that could still be happening in Dovecot code, but since the child
process quickly executes the actual program (the shell in this case), it
is more likely that this problem emerges outside Dovecot.
You can attach GDB to imap with follow-fork-mode set to 'child', so you
can maybe see what causes the segfault.

Stephan.
