libtool-symlist-name-null bug

[address@hidden]

Hi, libtool developers,

When I built pulseaudio with "--dlopen force", after that I found pulseaudio execution will cause a segment fault.
In pulseaudio ltmain.sh, lt_preloaded_symbols is set to "{0,(void *)0}".

The problem is at libltdl/loaders/preopen.c.

I checked the libtool-1.5.8, there is code block to check the same condition.
2053   while (lists)
2054     {
2055       const lt_dlsymlist *syms = lists->syms;
2056 
2057       while (syms->name)
2058         {
2059           if (!syms->address && strcmp(syms->name, filename) == 0)
2060             {
2061               module = (lt_module) syms;
2062               goto done;
2063             }
2064           ++syms;
2065         }

2067       lists = lists->next;
2068     }
