Hello! I know this is lot https://xkcd.com/979/ moment, but... have you figured out problem? :D

Same problem with qtwebengine 5.12.2 on armhf with debian stretch

Had the same issue using the OSELAS-2018.02.0 toolchain (gcc-7.3.1) for armv7a-hf. Fixed by upgrading to OSELAS-2018.12.0 (gcc-8.2.1). (Host is Arch Linux on x86_64)

I confirm, that there is a bug while using g++ v6 on armhf. It works with g++ v8, though Debian comes with standard v6, and "testing" repo must be used.

The problem wan be solved by applying this patch:
