FWIW, the problem disappears if I revert gcc-core and libgcc1 to 4.8.2-2.
JonY, do you have a chance to have a look into this issue?
Sorry, I have been busy these few weeks, but I am well aware that there
is a problem with one of the libgcc changes, but has yet to investigate it.
I believe Jon Turney has looked into it somewhat.
I think this is the same or a similar problem to the one I reported at
[1]. I also created a gcc bug [2], with a suggested patch.
Sounds good. Thanks in advance.
Yesterday I asked my collegues to take a stab at the issue and one of
them, DJ Delorie, came up with a libgcc patch already. It hasn't been
sent upstream yet. Can we give it a try, perhaps by creating a new
libgcc DLL, please?
Thanks, I'll get to it this weekend, should I make the new gcc an
experimental version? Or is just the libgcc binary required?
It's the libgcc DLL which gives us grief, so a new libgcc package is
sufficent, afaics. We should check if this DLL fixes the problem and
then make it "curr" soon, I think.
I briefly tested this other patch with my test case from the mail above,
and it doesn't seem to help.

No, I think it is an unforeseen consequence of the patch [3] to fix that
bug [4], which I believe is present in 4.8.3-1, introducing a new
problem when an executable which doesn't depend on libgcc dlopen()s a
dll which does.
