Even a simple

#include <setjmp.h>
#include "LPC11xx.h"

static jmp_buf end_out;

void main(void)
{
  setjmp(end_out);
  while(1) ;
}

leads to a HardFault. Any hints?!

Sounds like a potential issue in the C library. We'll investigate.

I'm curious... what do you want to use setjmp for?

in what time frame will the next version be released?

I'm using the setjmp in a piece of code ported from an AVR atmegaXX. It is part of a network stack and handles an asynchronous reset exception there. Replacing the longjmp would cause a major re-write of quite complex and extensively tested code.
