Bug (1): A totally clean, top of the CVS tree does not work on NT 4.0.
Behavior: returns with no result, any program.
Strange: Adding '+RTS -s' makes things work fine.
I think that there is not enough stack space on the C stack,
and the "change %esp register is failing us". The alloca
function is for this.

Here are two runs;
bash% ./main.exe
bash% ./main.exe +RTS -s
1) [2,4,6,1,3,5]
2) [3,6,2,5,1,4]
3) [4,1,5,2,6,3]
4) [5,3,1,6,4,2]
Here are two runs; both have a debug rts turned on.
bash% ./main.exe +RTS -D1
---- Initialised TSO 1 (0x141c0000), stack size = f3 words
scheduler: created thread 1, stack size = f3 words
Stack[2] (0x141c03f4) = 0x42bb3c FUN(0x414190, 0x402b08)
Stack[1] (0x141c03f8) = 0x42b0bc FUN(0x402b34)

Now here is the gdb run, with no arguments (the one that fails above)

Bug (2) BTW, attempting to compiled StgCRun, to use the Mini interpreter failes
with gcc 2.91.57 on NT 4.0:
StgCRun.c:43: warning: unused parameter `basereg'
StgCRun.c:43: warning: argument `f' might be clobbered by `longjmp' or `vfork'
StgCRun.c:62: fixed or forbidden register 4 (si) was spilled for class SIREG.
This may be due to a compiler bug or to impossible asm
statements or clauses.
