Subject: Crashes In Mini-Runtime on Ubuntu 14.04

Hey Mono-Dev,

I've recently been trying to debug a crash in the Mini-Runtime, and I'm unsure 
of where to look. The cause of the crash is a failed mono_domain_get (), which 
returns a null pointer at mini-runtime.c:2101
MonoDomain *domain = mono_domain_get ();

This causes a segfault at mini-runtime.c:2110
domain_info = domain_jit_info (domain);

Calling mono_domain_get after the segfault returns a valid appdomain, and this 
function is executed hundreds of times before segfaulting, so the appdomain has 
definitely been initialized properly.

Here is a backtrace of the state of all threads directly before the crash, the 
segfault occurs in thread 9.

I apparently don't have the latest version of mini-runtime, so my line numbers 
are slightly off from master (I'm running Mono 4.3.0, pulled and compiled on 
august 18th, for reference). The line numbers I'm referencing are in the 
official repo at:

https://github.com/mono/mono/blob/master/mono/mini/mini-runtime.c#L2097

https://github.com/mono/mono/blob/master/mono/mini/mini-runtime.c#L2106


Any direction would be appreciated,


-  Douglas Roffel

[Mono-dev] Crashes In Mini-Runtime on Ubuntu 14.04

2015-09-03 Thread Douglas Roffel 
According to that bug tracker, the issue was fixed in 3.13.0-54.91 for Trusty. 
My kernel version is 3.13.0-62-generic, which is newer than that.

Re: [Mono-dev] Class built by mono throws FileNotFoundException when run on windows

2015-09-03 Thread Greg Young 
Sorry it double posted as it was queued and didn't send and I sent it
again. Later my iPad apparently got wifi :) That's fair that you are
trying to avoid it but there are circumstances where it can be a good
idea. As an example if I wanted to start looking at your dependencies
with an analysis tool such as ndepend the dependency on mono.posix
might be an issue.
