Problem: Default autocorrect setting "Automatic *bold* and _underline_ changes the character format, but it doesn't disable the bold or underline character formatting after the second *, or _. Workaround: pressing Ctrl-B/Ctrl-U fix this autocorrection in the actual document.
1. Open a new empty document in Writer.
*bold* and _underline_ text
The word "text" in the result bold and underlined instead of normal text, see the attached screenshot.

Bad autocorrection in LO 3.6 and good one in LO 3.4
NOTE: After a single Ctrl-B/Ctrl-U in the document this autocorrection will work well, so it is a problem of the initial state.
that one is already fixed, just not in 3.6...
