Qt 5.14 branch (SHA ad2113fd235411f3669df8e6106dc7f5a760f9f8)
-
WebAssembly
Description
I'm experiencing a mysterious error when running make -j `grep -c '^processor' /proc/cpuinfo` for building the Qt 5.14 branch with Emscripten. This problem does not occur when building the 5.13 branch.
Following instructions on https://www.qt.io/blog/2019/03/05/using-docker-test-qt-webassembly

I don't see any errors in the build log that could have triggered the 2 return code, which makes this kind of strange.
Passing -skip qtdeclarative makes the build succeed. The problem therefore appear to be QML-related.
