terminate called after throwing an instance of 'trap_store_access_fault‘

[IC-Dream]

Hi, @poweihuang17 ,

when I use "spike -l --isa=RV32IMAFDC testMUL.elf >& out.log", I got the error: terminate called after throwing an instance of 'trap_store_access_fault', I have no idea about this, any help will be appreciated.

The gcc commad:

The .ld files:
/* not needed, but we need separate linker scripts anyway */
OUTPUT_ARCH(riscv)

/* required to correctly link newlib */
