I'm not sure what's going on there...
#5 0x2821bd7b in free (ptr=0x2abd81bc) at /usr/src/lib/libc/../libc/stdlib/nmalloc.c:774
#6 0x2ac93455 in operator delete (ptr=0x0)
#7 0x2ac27385 in __gnu_cxx::new_allocator<char>::deallocate (this=0x2abd81bc, __a=...) at /usr/obj/usr/src/world_i386/usr/include/c++/4.4/ext/new_allocator.h:95
Notice that in #7, you have this=0x2abd81bc and in #5 you have
ptr=0x2abd81bc. Not sure how to explain that...

I can't compile vlc any more. It fails during the build. The 2nd
backtrace is when I attempt to build vlc (it tries to run some program
as part of the build that winds up hitting the assertion).
