Test case

select_ast_4871_26_16832064820804524.zip

Build commands

I compile the code with commit id 7db4815e837bc34942e95aba292ca0eca318cc54. Platform: Ubuntu 20.04 CPU: amd64

compile:

export CC=/usr/bin/clang-14
export CXX=/usr/bin/clang++-14
cd product-mini/platforms/linux/;rm -rf build
cmake  -DWAMR_BUILD_INTERP=1 -DWAMR_BUILD_REF_TYPES=1 -DWASM_ENABLE_SIMD=1 -DWASM_ENABLE_BULK_MEMORY=1 -DWAMR_BUILD_AOT=0 -DCMAKE_BUILD_TYPE=Release -DWAMR_BUILD_FAST_INTERP=1 -DWAMR_BUILD_LIBC_WASI=0 -DWAMR_BUILD_LIBC_BUILTIN=1 -Bbuild
cd build
make -j40

execute:

iwasm --heap-size=0 -f to_test <tc_name>

Behavior:

I used the fast interpreter to execute the test case repeatedly 11 times, two of which triggered a crash. It is worth mentioning that the classic interpreter will not crash when executing this test case.

Crash 

Segmentation fault (core dumped)

The behavior of the fast interpreter image

The behavior of the classic interpreter image
