Updating to the latest live-git btrfs-progs (on v3.17.1 tag), I chanced across this (gentoo) warning, pointing to a gcc warning believed to be severe:
* QA Notice: Package triggers severe warnings which indicate that it * may exhibit random runtime failures. * cmds-restore.c:182:20: warning: array subscript is above array bounds [-Warray-bounds] * Please do not file a Gentoo bug and instead report the above QA * issues directly to the upstream developers of this software. * Homepage: https://btrfs.wiki.kernel.org A bit more context: cmds-restore.c: In function 'next_leaf': cmds-restore.c:182:20: warning: array subscript is above array bounds [-Warray-bounds] slot = path->slots[level] + 1; ^ Not being a coder I've no idea if it's a false-alarm or not, and I generally ignore these QA warnings since I've little hope of providing much more than the basic information or help, but since I'm already active here I thought I'd post it and see what happens. FWIW, gentoo/~amd64, gcc-4.8.3. Full build log available if needed altho I expect it should be easy enough to trace without. Note that I normally build with MAKEOPTS="-j10 -l8" so if log serialization is desired, please request a -j1 build log. -- Duncan - List replies preferred. No HTML msgs.
