The problem I fixed in js_msgbase.c rev 1.230 (Mar-13-2019 UTC) was introduced
in rev 1.226 of js_msgbase.c (Feb-12-2019). Calling any JS MsgBase method that
read from the index file before calling the get_all_msg_headers() method would
cause the error. I confirmed the error and the fix.

That's weird. Calling get_msg_headers() right after opening the messagebase did
not cause any error for me, nor should it have (the file pointer would be at
the beginning the file by default). I wrote a simple little script to executing
JSexec to 1. reproduce the error and 2. confirm the fix.
