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

Comment 2 Zoltan Varga 2013-02-27 11:08:39 UTC
How can I repro this ?
Comment 3 Marek Safar 2013-02-27 15:12:20 UTC
with 3.0 mt

- go to monotouch/tests
- make generate-sources-System.Core
- open bcl-tests/System.Core/System.Core.csproj
- build and run on device
Comment 4 Zoltan Varga 2013-02-28 09:33:38 UTC
Fixed. There are still several problems:
- about 85 tests fail, most of them are using decimals/nullables which are not yet supported by valuetype generic sharing.
- The TestBigUnion/ZipTestCase parallel tests take a _lot_ of time.
