apitrace replay --verbose --debug: stdout

NB: stderr attached separately.
Note that it stops after a certain swap buffers call, so I can only guess
something occurred leading up to that which would cause difficulty.

I note there are some attrib pointer calls in-between that and the previous
swap, which from my understanding of bug 105251 was one thing that could cause
crashes - however while that test program was fixed in the git build, this
issue was not.
I lack the knowledge to spot which particular call is the bad one though.
