--- Comment #1 from Timo Teräs <timo.teras at iki dot fi> ---
Simplifed commandline to:
armv6-alpine-linux-muslgnueabihf-gcc -Os -c -std=gnu99 aa.c -o aa.o

No ICE with:
armv6-alpine-linux-muslgnueabihf-gcc -c -std=gnu99 aa.c -o aa.o
armv6-alpine-linux-muslgnueabihf-gcc -march=armv7-a -Os -c -std=gnu99 aa.c -o
aa.o

So "-march=armv6 -Os" triggers the issue.
