[Chicken-users] Fixed stack size

[schugk]

Hi,

I am developing an application for an embedded device with chicken  
scheme 4.6.3. My program should use a fixed size of memory. I restrict  
heap usage with -:h500k .

./loop 10000 -:h500k -:hm500k -:hs0 -:hg0 -:D
...
[debug] heap resized to 512000 bytes
...
[debug] stack resized to 131072 bytes

With a lower heap size:

./loop 100000  -:h50k -:D
...
[debug] resizing heap dynamically from 51k to 500k ...

the heap size is changed. That is fixed with -:hm50K. But if i want a  
fixed stack size then my application terminates with:

./loop 100000 -:h500k -:hm500k -:s200K -:D

[panic] out of memory - cannot allocate vector (heap resizing  
disabled) - execution terminated

No stack resize message is shown for debug. Even a greater stack size  
of 2 or 8 MByte has the same effect. Why?
