Cannot compile c++ mp3 decoder project

[diamantisk]

I used the source code of https://github.com/FlorisCreyf/mp3-decoder in my project in order to build a cheerp .js file. After including the necessary parts of that project, compilation just failed, producing the following output:

The crash seems to happen while reading bytecode. Could you verify that all the intermediate bc files are being built using Cheerp with a consistent version?

[diamantisk (diamantisk)]

Yes, i confirm it. Im using the latest binary installation package for OSX,
as downloaded from Cheerp's website.

Can you provide the command you use to build the linked library using Cheerp?
