I'm not sure what's going on there...

ib/nmalloc.c:774

Notice that in #7, you have this=3D0x2abd81bc and in #5 you have
ptr=3D0x2abd81bc. 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).
