as re.dll should be loaded at 0x26f30000 but instead is loaded
at 0x660000 something is interfering.

Two possible reason:
- too many dll's. Look on "rebase -si" output to see
   what is the used range and if some are colliding ( the * reports them)

- some other programs are loaded in the same address.
   Look on /proc/self/maps for hint on space already used by system dll's.


I suggest to use 64bit cygwin when possible.
On 32 bit is too easy to collide.

Marco
