Description

I'm encountering some errors when trying to analyze the provided sample WebAssembly binaries. Is this an issue in my setup, or do you also encounter this issue?

Thank you for raising this issue. It seems you are encountering the issue with the heap running out of memory. We have also encountered this issue as well for larger files. For some larger files .wasm (less than around 20MB), they can be processed if the function call linking, which improves the detection rate, is disabled. This can be done by modifying commenting out Lines #2697-2699 in the Parser/parser.js file. In addition, the program may try to run the cached Redis abstractions, so you also need to uncomment Line #1740 to prevent the cached Redis values from being used.
