I'm having trouble reproducing the failure. Here's my commands:
> /scratch/tc-testing/tc-compiler-fuzz-trunk/build-gcv/bin/riscv64-unknown-linux-gnu-gcc
>  -O3 -march=rv64gcv -mrvv-max-lmul=m2 red.c -o user-config.out
> QEMU_CPU=rv64,vlen=128,rvv_ta_all_1s=true,rvv_ma_all_1s=true,v=true,vext_spec=v1.0,zve32f=true,zve64f=true
>  /scratch/tc-testing/tc-compiler-fuzz-trunk/build-gcv/bin/qemu-riscv64 
> user-config.out

GCC: r15-2297-g3adfcc58022
