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?!

taliesin,

We expect to make a new release of the LPCXpresso IDE within the next few weeks. If you would be interested in trialling the updated setjmp/longjmp, please contact us directly, referencing this thread:

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.

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

Just to confirm, we will fix this issue in the next LPCXpresso release.

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