The latest release of SEGGER's Embedded Studio for ARM comes with STOP technology, designed by SEGGER to reliably prevent stack overflows. With STOP enabled, the compiler adds a call to a stack limit-check routine wherever necessary, before adjusting the stack pointer.
The STOP option for the highly optimizing SEGGER Compiler can be easily switched on, without any change to application code. This way, all stack overflows are prevented. If a stack overflow has been prevented, the system can enter a safe state and recover.
STOP has a surprisingly low impact on size and speed: It adds only about 2
