This is likely due to: https://github.com/mesonbuild/meson/commit/b335ca2818b3cdb770bb69df25ae527d7ae8e7d3.

I'm checking with said patch applied.

Comment 2 Dylan Baker 2018-12-21 21:26:08 UTC

Indeed, it seems to be fixed by that patch. I'm planning to make 0.49.1 required for using ICC once it's out anyway (due to a lot of fixes in 0.49.0 and the fix to this in 0.49.1
