Thanks for this report! This indicates an sbrk failure, emulated here
in unexnt.c. If you can, try rebuilding with --enable-debug, you
should then be able to then run winedbg, which has elementary gdb
command capability. Break at sbrk, and step through, please, to see
where the failure occurs. There is a call to the wine-emulated
VirtualAlloc which I'm guessing is returning NULL. After the failure,
you can 'p DisplayError("foo")' to see the error output.
Non-wine related issues could be running with a limited .data segment
size constraint (e.g. ulimit -a), or a general configure error leading
to a bad heap size calculation.
I think wine also has a trace facility which should let you watch
VirtualAlloc. (Maybe set by environment variable as I recall?)
I have been told by the wine developers that the standard wine build
on a 64bit machine is an attempt at win64 emulation and is currently
highly experimental. I doubt this is what you are seeing, but it
might be wise to double check that everything is 32 bit here.
On that note, just a reminder if you could to post that failed win64
configure. That would be most helpful.
Take care,
