--- Comment #4 from A. Wilcox (awilfox) <awilfox at adelielinux dot org> ---
Even with -fno-guess-branch-probability (which is what we have put on our x86
builders so they run at all), rrdtool-1.7.0's rrd_resize.c has managed to make
the same lock happen yet again.

The only option that fixed it this time was -fno-tree-ter.

I will go ahead and upload the .i of the run with just
-fno-guess-branch-probability, in case that helps.
