When the cursor touches two (2) overlapping overlays, an incorrect display occurs under the following example:
* Both overlays contain the same priority, or no assigned priority.
* First overlay: . . . 'face '(:foreground "red" :weight bold)
* Second overlay . . . 'face '(:underline "yellow" :weight normal)
[The same result also happens if the bolded foreground face is a glpyh in the `buffer-display-table`, and where only one (1) overlay contains a *normal* weight underline. So, this issue does not appear to be exclusive to only the presence of overlapping overlays.]
The desired result is a bold foreground for the text, and a normal weight underline. That result can be achieved if the cursor does not touch the overlapping overlays. Once the cursor has touched the overlapping overlays, however, the underline takes on a *bold* visual attribute. This improper *bold* attribute may extend for the entire length of the overlay, depending upon which direction the cursor is moving and other overlays that may be present.
I was not able to correct this situation by setting priorities. In my various tests, setting priorities only served to choose one overlay over the other -- i.e., setting priorities do not permit the overlays to co-exist in harmony.
The thread that I opened on Stackoverflow contains some screen shots and a recipe to reproduce the error. It is not necessary to use flyspell or hl-line-mode to reproduce the error, that was simply the example I chose because it is the one where I always see the error. Perhaps the reason why the initial test by @Drew may not have yielded the same result is that his cursor was not touching "mal-normal" -- had his cursor touched that section of the buffer, the same result as I experienced may have occurred. I also use OSX, but it may not be an OS specific issue.

Here is the recipe -- just adjust the path to the `ispell-program-name`:

The recipe is somewhat convoluted, and I wasn't able to make it work
here. Do you have a simpler recipe? Since the issue seems to deal with
just the priority of some overlays, using aspell, fonts and hl shouldn't
be necessary?

More information was requested, but no response was given within a
month, so I'm closing this bug report. If the problem still exists,
please respond to this email and we'll reopen the bug report.
