Subject:	problems with dlopen
MIME-Version:	1.0

Hello!

Why does this code fail with segfault?
I think the problem is that dlopen calls malloc itself? Is that right?
Any suggestions how to fix it?

--snip--
#include <stdlib.h>
#include <dlfcn.h>

static void *(*orig_malloc) (size_t) = 0;

void *
malloc(size_t p)
{
        static int state = 0;
        void * handle;

        switch (state)
        {
                case 0:
                        handle = dlopen("cygwin1.dll", RTLD_NOW);
                        orig_malloc = (void *(*)(size_t)) dlsym (handle, "malloc");
                        state = 1;
                        /*fall through*/
                case 1:
                        return (*orig_malloc) (p);
        }
}

int
main()
{
        return 0;
}

  

--snip--

Best regards,
Henning
