Build artifact segmentation fault issue

[XYenChi]

Here comes the build steps from project readme.md:

$ cd riscv-vector-intrinsic-fuzzing
$ mkdir build; cd build
$ cmake ..
$ make
$ ./tool/random_gen

Here comes the test steps script to generate Makefile.
build steps from it:

$(GEN):
ifeq ("$(wildcard $(GEN))","")
	mkdir -p build
	cd build && cmake $(SRCTOP)
	cd build && $(MAKE)
endif

Add mask intrinsic related op to CustomOperator.def CI fail like the following:

Pass / Total: 2397 / 2400
Failed list:
 - MsbfM0VBoolVBVB111_m (GEN fail)
 - MsifM0VBoolVBVB111_m (GEN fail)
 - MsofM0VBoolVBVB111_m (GEN fail)

BUILD AND TEST with test steps

$ mkdir test
$ cd test
$ ../rif-test --cc=<YOUR-COMPILER-PATH>
$ make

Manually run the random_gen with this command:
build/tool/random_gen --root=MsbfM0VBoolVBVB111_m --nodes-to-gen=10 --length=5 --dot=MsbfM0VBoolVBVB111_m.dot --code=MsbfM0VBoolVBVB111_m.c --seed=3735928559 --march=rv64gcv_zfh_zvfh
compile:
{your RISC-V compiler path}/bin/riscv64-unknown-elf-gcc -march=rv64gcv_zvfh_zfh -O0 MsbfM0VBoolVBVB111_m.c -g -o msbf.g.elf
run:
{your qemu path}/qemu-riscv64 -cpu rv64,zfh=true,zvfh=true,v=true,vlen=256 msbf.g.elf
The testcase will not GEN fail, and result follow other issue.
But if follow the build step or download the ci artifact, will segmentation fault like this:
