Hi Kevin,

Thanks for the fast response.
It's regarding custom builds.


I've seen the mails regarding the MIPS issue, and therefore checked multiple configs
Failed combinations:

- GCC 5.5.0 & -Os
- GCC 5.5.0 & -O2
- GCC 7.3.0 & -Os
- GCC 7.3.0 & -O2

- Build OpenSSL with/without acceleration support
- Build kernel with/without FPU emulation



Checking 17.01 branch and trunk shows they both use dropbear release 2017.75.

Currently I'm custom adding the generated dropbear_host key from a pre-generated 17.01 build on the same device as a workaround.


Checking upstream dropbear I've noticed that libtommath has been bumped in the meantime (which solved a lot of reported issues I've seen passing by in mailing list), but for some reasons it takes upstream a VERY long time to release a new stable ..

I'll maybe try to switch openwrt to support git checkout on commit base ..

Thanks for the effort in commenting on this one!
