Smells of an optimizer/stripper bug :(

Patrick, Oscar, what specific build tools are you two using?

GNU ld (GNU Binutils for Debian) 2.22
gcc version 4.7.2 (Debian 4.7.2-5)
NASM version 2.10.01

Trying to recall if there's other utility packages.

I think we run the same building environment...

#cat /etc/debian_version
Debian 7.8 (64 bits)

#ld -v
GNU ld (GNU Binutils for Debian) 2.22

#gcc -v
gcc version 4.7.2 (Debian 4.7.2-5)

#nasm -v
NASM version 2.10.01 compiled on Jun 14 2012

#apt-cache show gcc-multilib
gcc-multilib_4.7.2-1_amd64.deb

#apt-cache show uuid-dev
uuid-dev_2.20.1-5.3_amd64.deb


Best,
Patrick

My build VM is 32-bit.

Oscar is on holiday for another week. But I'm pretty sure his 
environment should be:

(Sorry this was in my spam folder...)

Well it seems Oscar is building on a 64 bit platform...
