provoking ARB fatal error does not cause termination

[westram]

Reproduce:

cd $ARBHOME ; rm lib/arb_tcp.dat ; arb demo.arb

Instantly fails with

ARB: Internal ARB Error: ARB_DB_CLIENT_OPEN

but remains locked in launcher.

Notes:

• possibly related to #492
• arb apparently does not terminate!
• test #436 when fixed

Console output:

ARB: Internal ARB Error: ARB_DB_CLIENT_OPEN
(Reason: OPEN_ARB_DB_CLIENT ERROR: ARB ERROR: File $ARBHOME/lib/arb_tcp.dat missing or unreadable)
ARB: ARB is most likely unstable now (due to this error).
If you've made changes to the database, consider to save it using a different name.
Try to fix the cause of the error and restart ARB.

I think unrelated.

The error is triggered in gbcmc_open and passed down into load_and_startup_main_window, where it is ignored:

NT_main.cxx:204

        GB_ERROR problem = startup_mainwindow_and_dbserver(aw_root, autorun_macro);
        aw_message_if(problem); // no need to terminate ARB

Thereafter, the main loop simply continues to run w/o window.

I'm not sure what exactly is going on there. The startup of NT is split into a gazillion functions, so I cannot tell, what terminating on problem!=NULL would mean. It looks like macro replay is also done here (maybe NT is doing too many different things?), which is probably why the error is deemed non-fatal.
