32-bit applications on Windows normally only get virtual memory in the lower 2 GiB address space.
Because of memory fragmentation, VirtualAlloc() usually won't get 1 GiB of contiguous virtual memory in that address space. Therefore running system emulations with 1 GiB or more RAM will abort with a failure. The linker flag --large-address-aware allows addresses in the upper 2 GiB. With this flag, it is possible to run emulated machines with up to 2047 MiB RAM. Signed-off-by: Stefan Weil <s...@weilnetz.de> --- I tested the executables with large address awareness on a 64 bit Windows (works) and with Wine on Debian 32 bit Linux (no longer aborts, but hangs when 1024 or more MiB are requested). Maybe the support for large addresses is broken in my Wine version. Please report any different test results.
