Hello Dimitry,

Could you please give me an example of code that produce the error and versions of Linux and Mono you use? How often does the error occur? We test indigo-dotnet with Mono 2.10 on Debian Testing x64 and it works fine.

Hi Mickail,

Unfortunately I do not have code that reproduces this problem at this time. Linux version is CentOS 6.3, mono version:

mono --version Mono JIT compiler version 2.11.4 ((no/417ec78 Wed Feb 6 18:24:06 EST 2013) Copyright (C) 2002-2012 Novell, Inc, Xamarin Inc and Contributors. www.mono-project.com TLS: __thread SIGSEGV: altstack Notifications: epoll Architecture: amd64 Disabled: none Misc: softdebug LLVM: supported, not enabled.

Hello Dimitry,

I have tested Indigo 1.1.11 with same version of Mono on CentOS 6.4 and everything seems to work fine. Could you please provide a simple example of calling Indigo methods which cause the error? Does the application fail every time or not? Does the error occur at the end of executing application?

Just wanted to add that with everything the same (code and run-time condition) this doesn't happen with 1.1.10 of Indigo. Only with 1.1.11

Mikhail,

I was going to try and localize this, unfortunately next couple of week are going to be busy, don't think I will be able to get to this part soon. I was hopping that you might have some ideas about what kind of changes could have introduced this bug.

Dimitry, sorry for the long delay. I sent the release with debug information version of Indigo to your e-mail. It can give us additional information about the problem in native part of Indigo. Could you please reproduce the error using it and print the output here?

Hello Dmirty, We've just released Indigo 1.1.12. Could you check this version? Mikhail
