Compile error in asm

When I run GO111MODULES=on CGO_ENABLED=1 garble -seed=${SEED} build -race -o web/${NAME} and note the -race the following is thrown:

Getting rid of the -race flag, I found an issue in github.com/ebitengine/purego:

The latter can be solved using GOGARBLE on only our own packages.

We need some code to reproduce this
