Oh. I wasn't aware of an active regression here, but yes, that indeed
seems to be a known issue with 'upgrading' from 3.4 to current 4.x ...
I'm not sure what the current timeline looks like for a 4.3 release,
but it sounds like it hopes to resolve both this and Dwarf2 exception
handling, so that might be our cue to switch from the sjlj builds too.
I probably won't do a new upload just to add this note, but the race
will be on as to whether the next upload fixes it, or notes that it's
still an issue...
In the meantime, I've retitled this bug report, to hopefully catch
the attention of anyone else who gets bitten by this, in one of the
first places they might look when they do.
So far as I can see, the current most stable workaround is to go back
to the 3.4 toolchain if you need this. Hopefully not too many people
will need both it and fixes from 4.2 -- if you do, a static build that
doesn't throw across dll boundaries is probably your best answer right
now ...
Cheers,
Ron
