Nobody from the dev team uses this application, afaics.

To help tracking down the cause for the problems, can you bisect
Cygwin or at least check which of the snapshots from
http://www.cygwin.com/snapshots/ introduces the problem?

If this all occurs in ConEmu only, it may be one of the end of March
patches which may introduce incompatibilities with ConEmu's Windows
API hooking, but that's just a blind guess:

  6a06c6bc8f84 Cygwin: console: fix key input for native console application
  f4b47827cf87 Cygwin: console: Make I/O functions thread-safe
  8382778cdb57 Cygwin: console: fix select() behaviour
  bd627864ab41 Cygwin: console: support 24 bit color


Thanks,
