I can now reproduce the issue, after upgrading tcc to version 0.9.25
(either the issue wasn't present with the older version I had previously
installed, or I hadn't been able to trigger it).  I hope I'll be able to
find a fix before 1.11.4.  In the meantime, as usual, any help or patch
would be mostly welcome.

Thanks,
  Stefano
