" Signal Exception 0 received: A data abort exception has occurred..." when Debug N73

[nguyend]

Hi all,

I debug my app on N73 with Carbide C++ 2.3, I meet a exception:

Thread[Thread id: 1138] " Signal Exception 0 received: A data abort exception has occurred....

			TInt x = iAllMapRect.iTl.iX + iScreenSize.iWidth * c;
			TInt y = iAllMapRect.iTl.iY + iScreenSize.iHeight * r;
			TPoint p(x, y); // stop here, and throw exception, e32cmn.inl is showed and introduction pointer stop at function inline TPoint::TPoint(TInt aX,TInt aY): iX(aX),iY(aY)
			...

I have search on this forum but I haven't the way to solve this problem
Anybody can help me ?
Thank a lot!

I delete code TPoint p(x, y), replace by a function call, ex: this->CallFunction
And the exception throw at name of function
void CallFunction()
{
// I debug but, introduction pointer doesn't go into thi function, it stop at void CallFunction
....
}

May be I am meeting a Out Of Memory Error ?

Almost. It may be a stack overflow. Review your code for large entities (as simple C-arrays like "TInt a[100]", descriptors like "TBuf<1000> b"), if they happen to appear as local variables, either directly, or as part of even larger T-objects (for example "class TLargeData {public: TInt iManyNumbers[100];TBuf<1000> iLongText;};".

Anybody has another idea ?
Please, thank !

You can increase the stack size (EPOCSTACKSIZE in the .mmp, or the related setting in Carbide.c++'s .mmp editor). Depending on what your code actually does, it may delay the crash by seconds/minutes/years.

I find out stack size, and min max heap size, but I understand about them, can you show me about them, or do you have any link ?
Thank a lot !

My problem is out of memory, I have used many T Class with lagre size, I fix by use C Class with pointer

Thank a lot !
