Description Vaibhav Vaingankar 2017-04-25 09:50:33 UTC
Hi,
Greetings.

I am building ANTLR 4 (https://github.com/antlr/antlr4) 4.7 on IBM s390x architecture.

I have installed Mono (https://github.com/mono/mono) 4.8.0 for csharp runtime. I have encountered few test case failures related to csharp. The cause of the failure is delegate.execLexer in BaseRuntimeTest.java returns null. 

Since I have tried the same build steps on AMD x86 processor and it works fine, it is clear that this issue is specific to s390x architecture.

It seems the issue is with the Mono runtime built on s390x. I am not sure what the exact cause of this problem


Any guidance would be appreciated.

 
here is the bug I am am getting
