Emscripten command buffer error about vg-renderer

[jdryg]

Thanks for the report. Will take a look probably tomorrow. Yes, padding all commands to some predefined alignment should be the way to go.

I just pushed some changes regarding this bug.

The only way I could reproduce the crash was with -s SAFE_HEAP=1. Without it, WebAssembly (-s WASM=1) worked without a problem (as it's supposed to since it supports unaligned accesses), and asm.js (i.e. no WASM flag) asserted here https://github.com/jdryg/vg-renderer/blob/master/src/vg.cpp#L4368
But none of them crashed as they do with SAFE_HEAP=1.

Either way, please test it and report back as soon as you find the time.

@hugoam Any news on this one? Does it still happen with the latest version of the code?

Hey ! I might have confused WASM and asmjs when reporting the issue, it might have happened in the asmjs build. But it doesn't happen anymore in either of my builds, so I think your solution is perfect :)
