Hi Bernd,
Sorry, I had lost this in the mailing list noise.
I played a bit with the patch and different cases of figure. I am not able to understand
the purpose of each of your changes (due to the complexity of that particular code), but
I didn't find anything that stood out as wrong to me. Pedro might be able to do a more
in-depth review of the event handling code.
If the test tests specifically skipping of inline functions, I'd name it something more
descriptive than "skip2.exp", maybe "skip-inline.exp"?
Unfortunately, your test doesn't pass on my computer (gcc 9.2.0), but neither does the
gdb.base/skip.exp. I am attaching the gdb.log when running your test, if it can help.
Simon
