Thanks for the test program. I found the problem in the dynamic linker.
It's this new code in dlsym():
static void *
__dlsym(fd, sym)
void *fd;
char *sym;
{
struct so_map *smp = (struct so_map *)fd, *src_map = NULL;
struct nzlist *np;
long addr;
/*
* Restrict search to passed map if dlopen()ed.
*/
if (LM_PRIVATE(smp)->spd_flags & RTLD_DL)
src_map = smp;
The code doesn't take into account the fact that "smp" can be NULL. I
will commit a fix ASAP.
This could also (hopefully) be the cause of the core dumps that Masafumi
reported from running kaffe.
John
