Since you have a corefile, you probably have debugging symbols. Could you just
attach gdb and get a backtrace? Thanks!

gdb `which gpg-connect-agent`
run 'getinfo version' /bye

Thanks for doing this. Unfortunately, It seems that you don't have fully
debuging symbols. Can you please at least recompile Assuan with debugging
symbols so that the backtrace includes filenames and line numbers. Thanks!

iirc, we have another bug report related to this. Right now I am looking into
AIX problems.

Which libassuan version are you using?
libassuan-config --version
should show it.

I don't think it makes sense to wait longer for a response.

What we can take with from this report and similar in the past is that the
asprintf emulation (von gnulib) is troublesome. We should eventually replace
them by the libgpg-error printf functions. It is a dependency anyway. We only
need to bump up the required version.
