limits Problem

Adding debugging fails:

D0 duk_heap_alloc.c:621 (duk__dump_type_sizes): duk_re_compiler_ctx=196
D0 duk_heap_alloc.c:624 (duk__dump_type_limits): limits

However, it works under the host platform.

To compile on the host platform (the Mac):

gcc ../duktape2/src/duktape.c ../eduk2/duk_stack.c ../eduk2/nofileio.c ../eduk2/c_eventloop.c ../eduk2/modSearch.c ../duktape2/extras/print-alert/duk_print_alert.c ../duktape2/extras/console/duk_console.c ../duktape2/extras/logging/duk_logging.c ../duktape2/extras/module-duktape/duk_module_duktape.c -I../duktape2/src -I../eduk2 -I../duktape2 -c

g++ *.o *.cpp -I../duktape2/src -I../eduk2 -I../duktape2

D0 duk_heap_alloc.c:605 (duk__dump_type_sizes): duk_re_compiler_ctx=336
D0 duk_heap_alloc.c:608 (duk__dump_type_limits): limits
D0 duk_heap_alloc.c:611 (duk__dump_type_limits): DUK_INT8_{MIN,MAX}=[-128,127]=[-128.000000,127.000000]
D0 duk_heap_alloc.c:612 (duk__dump_type_limits): DUK_UINT8_{MIN,MAX}=[0,255]=[0.000000,255.000000]

Here's where the failure occurs in duktape.c:

DUK_LOCAL void duk__dump_type_limits(void) {
        DUK_D(DUK_DPRINT("limits"));

        /* basic types */
        DUK__DUMPLM_SIGNED(INT8);
...
#define DUK__DUMPLM_SIGNED_RAW(t,a,b)  do { \
                DUK_D(DUK_DPRINT(t "=[%ld,%ld]=[%lf,%lf]", \
                                 (long) (a), (long) (b), \
                                 (double) (a), (double) (b))); \
        } while (0)

The workaround is to edit duktape.c and make the following change:

#if defined(DUK_USE_DEBUG)
        duk__dump_misc_options();
        duk__dump_type_sizes();
        // duk__dump_type_limits();                                                                                                                    
#endif
