fp-stack-check, Qfp-stack-check

Tells the compiler to generate extra code after every function call to ensure that the floating-point stack is in the expected state.

Syntax

Linux and macOS:
-fp-stack-check
Windows:
/Qfp-stack-check
Arguments
None
Default
OFF
There is no checking to ensure that the floating-point (FP) stack is in the expected state.
Description
This option tells the compiler to generate extra code after every function call to ensure that the floating-point (FP) stack is in the expected state.
By default, there is no checking. So when the FP stack overflows, a NaN value is put into FP calculations and the program's results differ. Unfortunately, the overflow point can be far away from the point of the actual bug. This option places code that causes an access violation exception immediately after an incorrect call occurs, thus making it easier to locate these issues.
Alternate Options
None
