So it hangs in openssl.
I think that is a premature conclusion :)
I should have said:
"In this specific case, it was in openssl"
Which then is an observation.
But you could, next time, set a breakpoint at the line/address where it
returns to opm (or pascal code).

That should tell, if the socket call returns. (and then allow to find
where in the pascal code it loops (how many further frames back will it go?)

Which means the http request can not be aborted. (gracefully)
How up to date is your openssl?
System installed version, so 1.0.x. I recently updated my packages.
From the discussions on the git buck, it appears (I may be wrong) the
issue was fixed about one week back. (and then it depends when that made
it into your distro).
So if you recently updated, you may have updated to include the issue
(depends on the outcome of the above)
Anyway that is only one possibility.
Above gdb steps should get as closer to the issue (either if it is ssl,
or where in the pascal code to look for it).
----
As usual, the issue is that it does not (has not yet) happened to me
(Windows/Fedora 28).
Also I am not the maintainer of httpclient, nor of opm. So I can only
offer limited help. (I did have a look at opm in the past, so that's why
I jumped in)
