Subject: Re: dlsym(handle) may search in unrelated libraries
I accidentally added a crash. Namely exactly here:
> +static void load_deps_runtime(struct dso *p)
> +{
> + size_t i, ndeps=0, j=0;
> + struct dso ***deps = &p->deps, **tmp, *dep;
> + for (; p; p=(*deps)[j++]) {
*deps might be null pointer, which this expression is dereferencing.
Patch is attached.
Ciao,
Markus
