Note, that it doesn't happen only with 'rm', it's very random (cut, rm, 
cygpath etc)

I tried that (knowing that without debug symbols it wouldn't be too 
useful), but gdb then just hangs:

$ gdb c:/cygwin/bin/cygpath.exe 169

For what it's worth, my cygcheck -c -v -s is attached. Can maybe 
Christopher comment on the message from July last year?
