I checked the executable headers, and the default thread stack size is
set to 8Mb. "objdump -p emacs.exe" lists (among other things):
SizeOfStackReserve 00800000
SizeOfStackCommit 00001000
I also read the MSDN documentation for CreateThread and it looks like
the dwStackSize parameter represents the commit size unless the
STACK_SIZE_PARAM_IS_A_RESERVATION flag is passed to CreateThread. I
tried adding this flag, but it was not recognized by mingw so I
replaced it with the value (0x00010000).
When I recompiled, the resulting emacs would reserve 1Mb of stack for
each new thread. I than tried a few values for the dwStackSize
parameter and the smallest stack reservation I could obtain was 64K,
Here is the call:
cp->thrd = CreateThread (NULL, 64 * 1024, reader_thread, cp,
0x00010000, &id);
It also seems that the reserved stack size reverts to 1Mb if
dwStackSize is too small: the folowing values for dwStackSize will
result in 1Mb being reserved: 4, 1024, 4*1024 and the following
values will cause 64K to be reserved: 8*1024, 32*1024, 64*1024.
