ConnectionRequest looping with new iOS VM

[GoogleCodeExporter]

The scenario here is very similar to the import problems you have been working 
on, the difference is that instead of reading from a file installed on the 
device, we are reading the same data over the network from a PC application. 
Unfortunately that prevents me from creating a test case.

This is a regression, this function was working with the new iOS VM. Now that 
the file imports seem to be working fine, I can no longer use the network 
connection.

When I run my application on my iPod it seems to run into a problem at the same 
point every time, however the symptoms are different, sometimes it will lock 
up, sometimes it will crash.

Building the generated source code on Xcode, I see the same problem and again 
sometimes it locks up, sometimes it crashes. When it locks up Xcode shows 
memory use is constant and the CPU is running at 5%.

When it crashes it is on the assert in the following method:

void initMethodStack(CODENAME_ONE_THREAD_STATE, JAVA_OBJECT __cn1ThisObject, 
int stackSize, int localsStackSize, int classNameId, int methodNameId) {
#ifdef CN1_INCLUDE_NPE_CHECKS
    if(__cn1ThisObject == JAVA_NULL) {
        THROW_NULL_POINTER_EXCEPTION();
    }
#endif
    memset(&threadStateData->threadObjectStack[threadStateData->threadObjectStackOffset], 0, sizeof(struct elementStruct) * (localsStackSize + stackSize));
    threadStateData->threadObjectStackOffset += localsStackSize + stackSize;
    CODENAME_ONE_ASSERT(threadStateData->callStackOffset < CN1_MAX_STACK_CALL_DEPTH - 1);
    threadStateData->callStackClass[threadStateData->callStackOffset] = classNameId;
    threadStateData->callStackMethod[threadStateData->callStackOffset] = methodNameId;
    threadStateData->callStackOffset++;
}

I have some basic logging built into my app and it shows that we are connecting 
and receive the first few segments of the data, then it either hangs or crashes 
at the         networkManager.addToQueueAndWait(_connectionRequest);

Here is the log from a crash:

The thread stack in Xcode seems to show a recursive malloc. I have attached 
that as a file as it is rather long.

Hopefully you can see what is going on from this because I don't see how I can 
provide a test case unfortunately.

OK I see the issue. Its from a wrong assumption I made while fixing one of the 
other issues. Its fixed in SVN will try to get it into the servers tomorrow.
