Hi,

my application crashes sometimes with error "ExecutionEngineException".
This happens 1 time per week, since a few days it crashes nearly every
day.

On the computer the .Net Framework 1.1 and SP1 is installed. The OS is
Windows XP with SP 2. The error also occurs on a Windows 2000 Machine
(SP4).

I tried to debug the error in Visual Studio and found out that at first
an access violation occurs:

An Exception (first chance) at 0x79299450 in MyApp.exe: 0xC0000005:
Access Violation - Read0x00000004

After this error the ExecutionEngineException occurs and the programm
is terminated. No exception handler is called. Can I use the address to
find the code line where the error happens? I have no idea where to
search for this error. My application starts several threads.

Does anyone have an idea? It is very important that i fix this error.

Thanks in advance

André

In source code i found the line

-- Marshal.UnsafeAddrOfPinnedArrayElement --

Could this be the reason?

Yes.
