"Reloading" crashes the CardAndTerminalManager thread on GNU/Linux systems #22
Description
One of our customers has the following on average one time per day:

We do not know what the customer specifically does that might trigger this. We have a ton (1k+) of other customers running the same code on Windows and macOS, they do not have this problem at all.
Looking at the code, the whole "reloading" thing seems to be some kind of workaround in itself. It just happens to not (ever? not sure) work on GNU/Linux systems.
We are not 100% about this, but according to our crash reports, it seems that this problem started to occur since we switched from version 1.1.1 to 1.2.0 of the library. We need version 1.2.0 because of the improved support for foreigners' cards.
