Hi
I've been using Cygwin for a while and everything was working fine.
i've updated Cygwin to the latest version s 1.7.17-1. and even since
i'm unable to use it anymore.
I'm getting this message shown on every start of cygwin and it never
becomes operational:
0 [main] bash 6156 child_info_fork::abort:
C:\cygwin\bin\cygiconv-2.dll: Loaded to different address:
parent(0x490000) != child(0x630000)
bash: fork: retry: Resource temporarily unavailable
We usually associate fork() failures with a messed-up child process, but
that error message usually indicates that the parent is the one with
problems [1]. If you're starting from a command shell or other
persistent process, you might try restarting it in hopes that Windows
gives the next one a better address space layout. Otherwise, I don't
know what to tell you (WFM w/ same version of Windows), other than to
make sure things like SlickSVN aren't bundling some other version of
cygwin that's messing everything up (unlikely, since cygcheck didn't
complain).
[1] What likely happened is that Windows put "something" at 0x630000 and
forced cygiconv-2 to rebase; if that "something" moves out of the way in
the forked child, cygiconv-2 will then attempt to go where it "should"
go, giving a mismatch. For dynamically loaded dlls, cygwin can work
around this by unloading the library, and then filling the offending
address space with padding that forces it to go where desired, but
cygiconv is usually statically linked and therefore untouchable
(attempts to unload it are silently ignored by Windows).
i've tried rebaseasll, with a variety of open memory allocations but
nothing works.
I've had poor luck with anything but the default base address, because
the address space is crowded both above and below it. Fine line rebase
has to walk...
