I can re-produce this (same as above) and from within gdb, with a SEGV as a
result of both. I don't have a debug version installed, so if anyone else

Please do not inline cygcheck output, always attach it *to the mail*. It
create's false positives for those searching the archives, and can be a real

hits from people's mail that has inlined cygcheck output.
