Here's the really strange part:
if I do an strace on my application, then my signal handler

c.f. Heisenbug [1]. It's common enough, but very annoying. Gives you
another avenue to explore though. What does strace do to the
environment that causes the problem to disappear?
That's simple. strace is a Windows app, not a Cygwin app. So it doesn't
have the Cygwin signal semantics.
You'll probably get a better feel for the differences here if you take a
look at the Cygwin doc:

Gritty details can be found in 'how-signals-work.txt' the 'cygwin'
source directory.
