Dear Corinna, 

I have found your name on a `strace` log when using `dlopen` on Python. Is it normal?

symlink.check(C:\Users\user\Home\projects\foo\my.dll, 0x28AB88) (0x4022)
   35 2705178 [main] python2.7 16924 path_conv::check: this->path(C:\Users\user\Home\projects\foo\my.dll), has_acls(1)
   37 2705215 [main] python2.7 16924 cwdstuff::get: posix /cygdrive/c/Users/user/Home/projects/foo
   32 2705247 [main] python2.7 16924 cwdstuff::get: (C:\Users\user\Home\projects\foo) = cwdstuff::get (0x8006ECF0, 32768, 0, 0), errno 11
--- Process 14376, exception c0000138 at 7726163E

   36 2708611 [main] python2.7 16924 dlopen: ret 0x0

Depending if I use `python` or `ipython` I get a different behavior for cwdstuff:get. I don't know how to investigate on this. 

Here below what I get from strace when it works: 

symlink.check(C:\Users\user\Home\projects\foo\my.dll, 0x28B728) (0x4022)
   26 10440048 [main] python 12604 path_conv::check: this->path(C:\Users\user\Home\projects\foo\my.dll), has_acls(1)
   23 10440071 [main] python 12604 cwdstuff::get: posix /cygdrive/c/Users/user/Home/projects/foo
   25 10440096 [main] python 12604 cwdstuff::get: (C:\Users\user\Home\projects\foo) = cwdstuff::get (0x8006ECF0, 32768, 0, 0), errno 0
 3405 10443501 [main] python 12604 dlopen: ret 0x5B9C0000   


Regards,

This is the right place.

It is usually considered not polite to send e-mail directly
as highlighted on the problem reporting guideline:

This is not Cygwin's fault, AFAICS.  Cygwin never loads functions by
ordinal.  This is also a bit on the lean side as far as information is
concerned. One can't see how the process calls dlopen, for instance.
