Hi Syrone, Updating libtom makes sense, it's on the todo list.
I'm curious if it's a bug in old libtommath or new gcc. In my experience differences between optimisation levels are more often problems with the compiler, but could be either. If you could get a backtrace of a stuck "dbclient" built with gcc 7 it might be useful to see what's going on (and to know where to look in the libtommath commit log) Cheers, Matt > On Thu 1/6/2017, at 2:28 pm, Syrone Wong <wong.syr...@gmail.com> wrote: > > Hi all, > > Recently, I upgrade my LEDE toolchain to binutils 2.28 & GCC 7, notice > I cannot SSH to router. > > A more detailed description can be found > (http://lists.infradead.org/pipermail/lede-dev/2017-May/007753.html), > later, Kevin find it might related to libtommath > (http://lists.infradead.org/pipermail/lede-dev/2017-May/007797.html). > > Two possible solution: > > i. change libtommath compilation flag from -Os to -O2: > http://lists.infradead.org/pipermail/lede-dev/2017-May/007843.html > > ii. update the bundled libtom* to latest: > http://lists.infradead.org/pipermail/lede-dev/2017-May/007849.html > > Please update the bundled libraries to latest, or help to find the root cause. > > Thanks in advance > > Best Regards, > Syrone Wong
