SYMPTOMS

You run a kernel thread that uses Vector Floating-Point (VFP) instructions on a Windows Embedded CE 6.0 R3-based device. In this scenario, the thread may crash and you may receive many "Data Abort" exceptions.

CAUSE

This issue occurs because the kernel thread passes the stack address of an uninitialized local variable to the KCall function. When the variable locates the stack page, the variable finds that the page is uncommitted. Then, a "Data Abort" exception is triggered in the KCall function. Because the KCall function runs in a non-preemptive state, the Data Abort exception causes the thread to crash.

RESOLUTION
