Just as a data point, since I don't know gas the way Peter does. I get
the following errors when I run it with your code:

% ./yasm -p gas -f elf gastest.asm
% ld gastest.o -o gastest
ld: gastest: warning: allocated section `.text' not in segment
% ./gastest
zsh: exec format error: ./gastest

When I crossreferenced for the usage in our test cases, it uses ".text"
instead of ".section .text" so I tried that and it seems to execute
properly:

% ./gastest
zsh: exit 33    ./gastest

Peter will have to sort out whether this behavior is by design or by
accident. Since you say it works with as, I'm going to guess it's a
design oversight. And a great thing to catch before the final release of
0.5.0! :)
