  I can now, but not by rebasing to the exact same address; did something just
go amiss in your testing of that particular case maybe?


DKAdmin AT ubik /bin
$ rebase -v -b 0x6b500000 ./cygmagic-1.dll
./cygmagic-1.dll: new base = 6b500000, new size = 20000

DKAdmin AT ubik /bin
$ ./file.exe ./file.exe
      1 [main] file 1556 _cygtls::handle_exceptions: Error while dumping state
(probably corrupted stack)
Segmentation fault (core dumped)


  It's reversible, too!


DKAdmin AT ubik /bin
$ rebase -v -b 0x6a500000 ./cygmagic-1.dll
./cygmagic-1.dll: new base = 6a500000, new size = 20000

  Ok, now I'll try debugging it.
