System Information
Operating system: Ubuntu 16 and 18 and also Debian, all tested via Docker
Graphics card: -

Blender Version
Broken: 2.81.3 master e283f0807c60
Worked: There was no such problem on MacOS Mojave

Short description of error
The whole compilation and install process works like a charm. However you cannot enable OSL with Cycles and render. The following error occurs:
Fra:1 Mem:126.54M (0.00M, Peak 128.94M) | Time:00:00.22 | Mem:0.00M, Peak:0.00M | Scene, RenderLayer | Updating Scene
Fra:1 Mem:126.54M (0.00M, Peak 128.94M) | Time:00:00.22 | Mem:0.00M, Peak:0.00M | Scene, RenderLayer | Updating Shaders
Couldn't find function osl_raytype_bit
/root/src/blender-deps/OpenShadingLanguage-1.9.9/src/liboslexec/llvm_util.cpp:1240: failed assertion 'func'
Aborted

Exact steps for others to reproduce the error

Compile dependencies with install_deps.sh --with-all
Compile Blender
Start Blender
Set Cycles as render engine
Enable Open Shading Language
Save your scene under osl_test.blend
With the command line, call blender -b osl_test.blend -f 1
The error above occurs. Note that we haven't yet used any OSL feature.
