I am wrapping a FORTRAN library that has a bunch of STOP commands in it (to throw errors). However, when I call the library from Julia and one of those errors is reached, the whole process exits (including the Julia REPL). Is this expected? And if so, how can I get around this behavior and simply let an error be thrown on the Julia side of things (`try` `catch` doesn’t seem to have effect here)?

Yes it is expected and no there’s basically no way around it. You need to patch those away to report the error in a different way and recompile the FORTRAN library . This is exactly why such code should never be used to report errors in a library, just like abort in C.

Alright, so the fun begins. Thanks for the help!
