1.5.25: Random segfaults in unix tools

I'm using Cygwin to provide the UNIX utilities such as sed, awk, cut etc. to a Windows server. This process works correctly on our dev server, but when using the same shells and Cygwin install on our prod box these tools randomly segfault.

The processes will work a number of times (seemingly random), but after a few runs will invariably begin to segfault as shown below, the only solution is to bounce the box and we get a few more runs before futher segfaults.

Exception: STATUS_ACCESS_VIOLATION at eip=8B909090

19 [main] cut 1620 _cygtls::handle_exceptions: Error while dumping state (probably corrupted stack)

What is causing the segfaults and how can it be resolved?
