STATUS_FLOAT_MULTIPLE_FAULTS

What STATUS_FLOAT_MULTIPLE_FAULTS means

STATUS_FLOAT_MULTIPLE_FAULTS (0xC00002B4) is an exception status for multiple floating-point fault conditions. It is not a generic Structured Exception Handling tutorial and the status alone does not identify which floating-point condition should be blamed.

What to inspect

• Capture the exception record, faulting instruction pointer, thread, and the floating-point instruction that triggered delivery.
• Preserve the thread's floating-point control and status state, including the SIMD or x87 environment relevant to the instruction.
• Distinguish this status from neighboring floating-point exception values before changing arithmetic or exception masks.

Recovery

Correct the arithmetic input or floating-point environment that produced the fault and rerun the same operation. Do not infer division-by-zero, underflow, or another specific condition from this status without the processor and exception-state evidence that identifies it.
