System.StackOverflowException when using ZeroC Ice 3.4.2 on Mono 2.10.x

[miltondp]

I have reported this bug in the Mono bug tracking system here:

Bug 2449 – System.StackOverflowException when using ZeroC Ice 3.4.2 on Mono 2.10.x

However, one of the developers suggested to file a bug in these forums as well, as you likely have more information to resolve it.

Take a look please at the bug link for the complete bug report. I've also attached a file with a trace of the exception. The problem seems to reside in this method:

IceInternal.AssemblyUtil.loadReferencedAssemblies (System.Reflection.Assembly)

Hi Milton,

Thanks for reporting this. If it is a Mono bug, we'll try to find a workaround that we can include in the next release.

Milton,

I've been doing some testing with Mono 2.10.8 on SLES 11 but haven't been able to reproduce the problem you described. Of course, the problem may be dependent on your application structure, such as how many assemblies are used in your server, where the Slice-generated code is located, and so on.

Would you be able to provide a small test case that we can use to reproduce this problem?

If not, can you describe in detail the assembly structure used by your server?

Thanks,
Mark

Hi Mark, thanks for your reply.

I just installed Mono 2.10.8 on Fedora and I was able to reproduce the problem. I'm planning to upload the source code of my app soon so you can play with it. Will let you know when it's ready.

Thank you!
Milton.

Hi

Have you prepared your codes yet? If so, i would like to run on my machine and try to find out what happens.

Thanks..

Sorry for the long delay guys!

You can download the source code from this URL. These are the steps to reproduce the problem:

1. Navigate to the src/Stratos folder.
2. Run the "make" command (it uses xbuild).
3. Configure Stratos Server to run against SQLite (so you don't have to have a database server to test it): move to src/Stratos/StratosServer/build and run: cp ActiveRecord.config.sqlite.xml ActiveRecord.config.xml
4. Start the Stratos Server: go to src/Stratos/StratosServer/build and run the command: mono StratosServer.Startup.exe. Now the server is listening for incoming connections.
5. Start the Stratos Client (Gtk app): go to src/Stratos/StratosClient/build and run the command: mono StratosClient.Startup.exe
6. When starting the Client, you'll see it freezes at startup. Take a look at the Server console, you'll see messages like this:

   Stack overflow in unmanaged: IP: 0x82266c9, fault addr: 0xb3f07fbc
   Stack overflow in unmanaged: IP: 0x82266c9, fault addr: 0xb3f07f0c
   Stack overflow in unmanaged: IP: 0x82266c9, fault addr: 0xb3f07eec

Let me know if you have any problem. And sorry again for the long delay.

Thank you.
