And it crashed 3 times. I moved back to 2.8.5dev.14 and it
doesn't. I don't know if it's a Cygwin bug.

I attached what I got with drwtsn32.

The Event log has

Faulting application lynx.exe, version 0.0.0.0, faulting module
cygwin1.dll, version 1003.22.0.0, fault address 0x0004061f.

The application, E:\cygwin\usr\local\bin\lynx.exe, generated an
application error The error occurred on 04/30/2003 @
20:28:27.322 The exception generated was c0000005 at address
6104061F (cygwin1!mktime)

The 3 crashes are identical. 0x0004061f, c0000005, and 6104061F
(cygwin1!mktime).
