Re: [Ikvm-developers] DLL generated using IKVMC causes Visual Studio 2008 Debugger to terminate abnormaly

[Jeroen F. <je...@su...>]

Hi Rolan,

I don't know what's going on. Some questions:

- does the project include native code?
- could it be a stack overflow?
- could any code be calling System.exit()?

Regards,
Jeroen

Subject: [Ikvm-developers] DLL generated using IKVMC causes Visual Studio 2008 Debugger to terminate abnormaly


Hi all,

When I try to debug the .Net application which calls an IKVMC generated dll, the debugger will unexpectedly crash in an unexpected point.

- The crashes will start only after a call to the code from the  IKVMC generated dll (even if it was done in run, not in step-over).
- The crash can be one of the following:
        - Returning control to the running application as if you pressed F5
        - The running application would quit with no error.
        - The debugger stays in debug mode, with no control, and the application form closes.
- The line where the debugger crashes doesn't have to contain a reference to the code from the dll.
   for example i made a For loop that does multiple Debug.print(), and it would randomly stop in different lines
- "Enable unmanaged code debugging" checkbox in the project properties doesn't help, thuogh for some projects it helped.
- Tried the  IKVM 38 build, didn't solve the problem.
- Tried using the -debug command line switch to generated the pdb files for the studio debugger, but it didn't help neither.

About my app:
Using visual studio 9 SP1
java version 1.4.2
I generate DLL's using IKVMC.0.36
The java application consists of JAXB, xml manipulations, and MQSeries calls, using the following jars:
jaxb-impl-1.0.6.jar, jaxb-api-1.0.1.jar,connector-1.0.jar , com.ibm.mq-6.0.0.jar, jax-qname-1.1.jar, namespace-1.0.1.jar, xsdlib-1.0.jar, relaxngDatatype-1.0.jar, xercesImpl-2.6.2.jar
The java code has multiple modules, mainModule, and subModule1, subModule2, submodule3.... etc.
The main module is built using the command:
ikvmc.exe -out:mainModule.dll -target:library -keyfile:XXX.key mainModule.jar jaxb-impl-1.0.6.jar com.ibm.mq-6.0.0.jar....
The sub-module built using the command:
ikvmc.exe -out:subModule.dll -target:library -keyfile:XXX.key -reference:mainModule.dll subModule.jar


thanks in advance,

Rolan.
