Incorrect Handling of Call Instructions in wasm-interp

[Q1IQ]

wasm-interp encounters an "Aborted (core dumped)" error when executing a WebAssembly module that contains call instructions. This issue leads to an unexpected termination of the program.

Test case

program.wasm.txt

Environment

• OS: Ubuntu 20.04
• CPU: amd64
• WABT version: 1.0.36
• Commands:

./wasm-interp --enable-all --run-export=main ./program.wasm

Actual behavior

Aborted (core dumped)

Expected behavior

wasm-interp should execute the call instructions without causing an "Aborted" error. If there is an issue with the module, it should provide a descriptive error message instead of terminating unexpectedly.
