OK, I have caught it. So I am going to prepare a patch to fix all
those debug stuff. Just tell me which of the following two versions do
you prefer.

1st version:

void foo(void)
{
#ifdef NUTDEBUG
#ifdef ARCH_32BIT
    static prog_char fmt[] = "SWC<%08lx %08lx>";
#else
    static prog_char fmt[] = "SWC<%04x %04x>";
#endif
#endif

    do_something();

#ifdef NUTDEBUG
    fprintf_P(__os_trs, fmt, level, (uptr_t) runningThread);
#endif
}

2nd version:

void foo(void)
{
    do_something();

#ifdef NUTDEBUG
#ifdef ARCH_32BIT
    fprintf(__os_trs, "SWC<%08lx %08lx>", level, (uptr_t) runningThread);
#else
    fprintf(__os_trs, "SWC<%04x %04x>", level, (uptr_t) runningThread);
#endif
#endif
}

Regards,
/J.D.
