Description

$MaxStackSize set the program’s maximum stack size in bytes. A library ignores this compiler directive because a DLL does not have its own stack. The default maximum stack size is 1 MB (1048576 bytes), which is more than adequate for most programs.

Windows creates the stack with the minimum stack size specified with the $MinStackSize directive, and the stack grows as needed, up to the maximum size. If the stack size reaches the maximum size, Delphi reports runtime error 12 (EStackOverflow).

In most programs, if you get a stack overflow error, it is due to a software defect, such as unbounded recursion. Check closely for mistakes before you increase the maximum stack size.
