What does the output of `rebase -is' show? Any conflicts (marked with
'*')? Mine uses the address range 0x5fe50000..0x6fff7000, with
cygiconv-2.dll residing at 0x67200000. Which made me notice that...

... OP's base addresses seem to be missing a trailing zero digit. Or
two. What kind of rebase run would have done that?
Those low addresses are really crowded with Windows stuff, it's no
wonder forks are failing when dlls land there; for me, 0x630000 is in
the middle of a thread stack, and 0x490000 is the middle of the default
Windows heap. Granted, both are subject to ASLR, but I tried multiple
times and there was always something at those two addresses.
For both of you, what gets printed if you fire up cmd.exe, cd to the
cygwin/bin dir, and invoke `cat /proc/self/maps' ? That should always
succeed, because it doesn't call fork().
