runtime: Dotnet 'myApp.dll' hang in lttng running on arm32

Running a very framework dependent console application with the command ‘dotnet myapp.dll’ causes a hang running on a simple yocto image on an Rpi3 (arm32)

Running dotnet --info produces the expected output of

Version : 2.0.0 Build : e8b8861ac7faf042c87a5c2f9f2d04c98b69f28d

but running any application including a very basic app that simply writes to the console completely hangs with zero output to the terminal.

Running with COREHOST_TRACE=1 produces similar output to what is seen running the app on another Linux machine but it hangs before the expected line “Property TRUSTED_PLATFORM_ASSEMBLIES = …”

The ‘installation’ has been from the binary release at https://dotnetcli.blob.core.windows.net/dotnet/Runtime/2.0.0/dotnet-runtime-2.0.0-linux-arm.tar.gz

The final few lines of output before hanging are

Considering entry [runtime.linux-arm.Microsoft.NETCore.DotNetHostPolicy/2.0.0/runtimes/linux-arm/native/libhostpolicy.so] and probe dir [/opt/dotnet/shared/Microsoft.NETCore.App/2.0.0] Local path query exists /opt/dotnet/shared/Microsoft.NETCore.App/2.0.0/libhostpolicy.so Probed deps json and matched '/opt/dotnet/shared/Microsoft.NETCore.App/2.0.0/libhostpolicy.so' The resolved JIT path is '/opt/dotnet/shared/Microsoft.NETCore.App/2.0.0/libclrjit.so' CoreCLR path = '/opt/dotnet/shared/Microsoft.NETCore.App/2.0.0/libcoreclr.so', CoreCLR dir = '/opt/dotnet/shared/Microsoft.NETCore.App/2.0.0/'

At this stage ctrl+c has no effect and the process needs to be killed to recover the terminal

The full output is attached along with the application
