Re: [DEV-C++] BUG: Dev-C 4.9.20 consolprogram has only access to 1MB memory.

[staale <st...@le...>]

Hi again Ioannis and Helmut,

Your sample code (yes the application crashes, not the IDE) died (stack
overflow) at Approximately 2002 kB on (Nt4-Sp6 - Dev-C 4.9.20).

On NT4-SP6 Dev-C 4.0 I got 32250 kB before I got a stack overflow error.

The w2k machine with first Dev-C 4.0 and then 4.9.20 installed got the stack
overflow at 2002 kB.

So we could conclude that the two versions of Dev-C (or rather accompanied
compilers) handels stack allocation differently?

Regards
Staale Flock
