As someone else already pointed out, you should never have more than one
version of the cygwin1.dll loaded at the same time. From the getdp README:

1) About cygwin1.dll:

If you plan to use other programs than GetDP that depend on the
cygwin1.dll library, you should keep only one version of this library
on your system (i.e., move cygwin1.dll to the Windows system
directory--usually C:\Windows\System\--and suppress all other versions
of cygwin1.dll). Failing to do so may result in an incorrect behaviour
of applications sharing the library and running simultaneously.

You can launch getdp directly from the graphical user interface. Copy
getdp.exe in the same directory as gmsh.exe, launch gmsh and click on
getdp in the solver menu. Et voila ;-)
