So ideally we need some code that exposes the bug when using -O2 (or even just -funroll_loops) Looking at FS 814 there’s a hint in there that uhttpd was similarly affected…and not solved by the patch drop.  So what to do if there’s a bug just lurking to bite us?

Hi,

The attached patch also made the problem disappear.
This patch builds the code with -funroll-loops in addition, otherwise
only the default settings are used.
