Hmm I can't reproduce either.

riscv64-unknown-linux-gnu-gcc -march=rv64gcv_zvl512b1p0 -mabi=lp64d -O2
990128-1.c
QEMU_CPU=rv64,v=true,xventanacondops=true,x-zvfh=true,zfh=true,zba=true,zbb=true,zbc=true,zicond=true,zicboz=true,zvbb=true,vext_spec=v1.0,vlen=512

riscv64-unknown-linux-gnu-g++ -march=rv64gcv_zvl128b -mabi=lp64d -O3 bla.cc

I'm expecting an abort but nothing (I hopefully don't need to inspect the data
manually?).  Do I need other settings?
