it turned out that the mentioned commit was not the actual cause of the ICE, but a very similar one:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=90139

(https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=275156)

I can confirm that with GCC 5.4.0 with this patch applied it was
possible to build QtWebEngine 5.13.0 for armhf
