redBlack test failed

[clover2123]

redBlack.wasm test is failing, and it looks like it may be difficult to resolve quickly.

Original redBlack.c file : https://github.com/Samsung/walrus/blob/main/test/wasmBenchmarker/ctests/redBlack.c
Related action: build-test-performance-x64_x86 (x64)

I checked about this issue, and found that emcc version 3.1.6(installed with apt) makes redBlack.wasm file which is working well on walrus.

So, I think emcc version 5.0.5(current latest version, and version used at build-test-performance-x64_x86) or earlier between the last PR which do not have this issue is related to this error.

Great, thanks for the analysis.

It seems that the latest version of emcc generates WebAssembly code somewhat differently from older versions. We may be able to debug this issue by first comparing the two generated .wasm files and then investigating the newly generated wasm code in more detail.
