crash after upgrading mono to 4.4.0

[webarchymeta]

Our services on ubuntu 14.04 runs well before the upgrading (and it continue to be so after the upgrading for a while). But today, it starts to crash on starting up:

Error: No managed allocator, but we need one for AOT.
Are you using non-standard GC options?

Debug info from gdb:

=================================================================
Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
=================================================================

Aborted (core dumped)

I know it may not be the problem of edgejs. But does any one also experience such a crash here? Is there any way to solve it?

I noticed the same after upgrade to Mono 4.4.0. Temporary workaround is to pin to Mono 4.2.4. This is what I do in another project:

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF && \
  echo "deb http://download.mono-project.com/repo/debian wheezy/snapshots/4.2.4 main" | tee /etc/apt/sources.list.d/mono-xamarin.list && \
  echo "deb http://download.mono-project.com/repo/debian 40-security main" | tee -a /etc/apt/sources.list.d/mono-xamarin-security.list && \
  echo "deb http://download.mono-project.com/repo/debian wheezy-libjpeg62-compat main" | tee -a /etc/apt/sources.list.d/mono-xamarin.list && \
  apt-get -y update && \
  apt-get -y upgrade && \
  apt-get -y install pkg-config libgdiplus mono-complete alien libaio1

The key part being:

echo "deb http://download.mono-project.com/repo/debian wheezy/snapshots/4.2.4 main" | tee /etc/apt/sources.list.d/mono-xamarin.list

I will be fixing Edge install scripts to that effect after another major PR for CoreCLR is in.
