@herrtimson we already confirmed that the gcc-7 / Bionic build crashes
on the exact same misaligned instruction in Skia. See responses #48 and
#50 for how I tested this, the point being that waiting for Bionic alone
won't fix this.

Diagnosing a corrupt stack: whether you have debug symbols or not you
should run this in gdb: layout asm. This will tell you if it's the same
Skia illegal/misaligned instruction, the earlier SIGSEGV crash at strd
r2, r3, [r1], or something else. Because levente was using a 16.04 deb
he was most likely hitting the known SIGSEGV. Would be good to identify
your build's crash because we don't have any other datapoints for gcc 6.
