Sample solution generating memory leak
On Debian 64, linux 3.11.4.
When using ThreadLocal type in specific configuration there are visible memory leaks in the application.
Issue is confirmed to occur both on sgen and boehm GC, the difference is in the speed of memory usage growth.
Step to Duplicate:
1. Open sample solution attached to this report and build it.
2. Start it under sgen or boehm (mono --gc=boehm Threader.exe or mono --gc=sgen Threader.exe)
3. Observe process memory usage changing in time (with system monitor or just ps command).
What is interesting, commenting out the field 'tli' in ExampleClass fixes the problem same as removing one field in ExampleStruct (in fact it seems that structs of size 12 bytes or more causes problems).
working on it.
Fixed in master.
