With the latest updates in #57 (as of c93eb46), I have: Hera fails two tests st.whitelist(`^stEWASM`)

As of fc424d7, all tests are passing with Hera. But something is still clearly broken for SSVM, eg. Run the script above to reproduce failures on a test-by-test basis. @dm4 Can you give a hand here? |

Hi, @me020523 |
|
Update: It looks like SSVM get lots of wasm module instantiation errors. Please give me a moment to analyze these wasm bytecode. |
|
Update: You can check out to our master branch to get the latest code.

System and Version Info
feat/evmc6]139dbb5791e46d9c0edea9defd8f9231023fe7cbExpected behaviour
Hera and SSVM EWASM libs should be able to pass stEWASMTests.
Actual behaviour
Full log attached: test.ssvm.log
At this point I'm not sure if this is an issue with SSVM, the go-ethereum/
evmcCGo bindings, or thecore/vm/evmc.goimplementation. cc @dm4 Would you be able to help here?Hera actually seems to throw a comparable error (not sure if on the same specific tests), but doesn't Fatal itself. The code originally caused geth to panic when the EWASMs returned an internal error. Returning the error seems to fix the tests, for hera...https://github.com/etclabscore/core-geth/pull/57/files#diff-9633a3aa7f6fd345efaab4431bab4ae8R379-R381You can make Hera fail the tests by reverting this commit.skipLoadsection for them for now -> Feat/evmc6: stEWASMTests fail (internal error -1) #62 (comment)Steps to reproduce the behaviour
