Address space is limited on NT that is way only 125 tasks.
By default gnat 304 links with -stack 0x1000000,0x10000
This meants that the stack reserve size is 0x1000000.
Since the user address space size is only 0x80000000 maximum
128 stacks for tasks kan be reserved. Thats way the limit of
about 125 tasks.
If you change this into a smaller stack reserve size then you
will be able to create many tasks in your ada program.
The -stack option can be found in the file specs.
