The latter are no, a reduced test case is attached gcc -O3 bug.c fails, but gcc -O3 -fno-tree-slp-vectorize bug.c passes, so CFLAGS+=-fno-tree-slp-vectorize is a workaround. probably related to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68517 (although i dont see 0 sized structs here), but i could not reproduce it with another toolchain, only with the alpine x86_64 gcc-5.3.0 one.
