vlc-2.1.1 build fails on FreeBSD-9.2/amd64

[Jukka Ukkonen]

Hello,

I tried to dig a bit into the issue why vlc-2.1.1 fails to build properly.

*The last lines of output from the build* (triggered by portupgrade) are...

*The failing binary* apparently is
/usr/ports/multimedia/vlc/work/vlc-2.1.1/bin/.libs/vlc-cache-gen


When running manually make with *ktrace* like this...
ktrace -dit+ make

... and then *kdump* right after that produces this snippet of output
around the moment when everything goes pearshape...

I hope this helps.
