2.3.2 /Gs

CLAXP supports the /Gs option to turn-off stack limit checking, but does not support the form /Gsnum to specify the stack-limit checking value. In particular, use /Ge to enable stack limit checking (the default), not /Gs0.

When stack limit checking is enabled, it is assumed that there may only be a single guard page for a thread. For the Alpha AXP architecture, a hardware page may have a size of 8, 16, 32 or 64K bytes, depending on the implementation. The CLAXP stack checking logic is thus based on the minimum allowed page size of 8K bytes.
