I been having a problem where HeapAlloc is failing
even though there's plenty of virtual memory left
I've done a bit of digging but haven't been able to
get to the bottom of it.
First of all I've checked that HeapAlloc will go into
swap by allocating a lot of 64meg blocks and writing
to them to force linux to allocate them properly, and
it works fine.
Then I changed alloc.c so that CreateSubHeap writes
the status returned by NtAllocateVirtualMemory and I
get C00017 STATUS_NO_MEMORY.
HEAP_CreateSubHeap Could not allocate 00410000 bytes
reason: C00017 [STATUS_NO_MEMORY]
an I double checked this by putting a malloc in just
after the failure, which failed.
So then I wrote a a small non-wine test program run as
a seperate process to allocate ten times as much ram
and ran it while just after the crash (while the debug
box was still up) and it works fine.
