IA_32_Exception (StackFault) – Stack Fault
Name
Cause IA-32 defined set of stack segment fault conditions detected during stack segment load
operations or memory references relative to the stack segment, refer to the Intel
and IA-32 Architectures Software Developer's Manual for a complete list of all
IA-32 faulting conditions. Stack faults can also be generated when the processor
detects an inconsistent stack segment register descriptor value during an IA-32 stack
reference instruction (e.g. PUSH, POP, CALL, RET,). See section
and Environment Integrity"
conditions.
Parameters IIP – virtual IA-32 instruction address zero extended to 64-bits.
IIPA – virtual address of the faulting IA-32 instruction zero extended to 64-bits.
ISR.vector – 12.
ISR.code – IA-32 defined ErrorCode. Zero if an inconsistent register descriptor is
detected during a memory reference relative to the stack segment.
