After successfully compiling SPEC2006 using the above configuration, the
following problem will occur in 403.gcc when running the intspeed/test data
set.

gcc_base.riscv: internal error: 4
It is possible that you may be trying to use SPEC's version of gcc
without first defining the appropriate flags.  Please check the flags
that are in the config files from recently-published results on your
platform, and check that you are using an up-to-date compiler.  If
you still need help, please contact SPEC, reporting your hw/os
platform, your compiler version, and your compilation flags.

Similar error will occur when running the simulation in user mode in qemu. The
running command is as follows:  

# qemu version  
qemu-riscv64 version 8.2.93 (v9.0.0-rc3-5-g824ebb92c3)  

#running command
qemu-riscv64 -cpu rv64,v=true,vext_spec=v1.0,zicond=true ./gcc_base.riscv

Does adding -fno-strict-aliasing help?

After adding this compilation option, the same error will still be reported
