I tried key generation with and without pre-setting a password using git
commit 11142e0ad7bc9a9e3c3dccf958d8dbd3312cb993.

Key generation works fine if used with --batch (like above, and also by
specifying the parameters via stdin). However, when the password should
be queried via pinentry, I get a segfault. Password inquiry via
gpg-agent/pinentry works for all other use-cases.

Below is the output with --debug-level guru:
