Maybe. The error message is printed when exp_getptymaster() (in pty_unicos.c) returns -1. It's hard to follow exactly what that function does. It has a log of diagnostic log lines (expDiagLog(...)) but I can't figure out how to get Expect to print those diagnostics. I could try adding some paths to the sandbox whitelist.
