Android program crash with signal 11 and fault address

Question

I searched and found a lot of signal 11 reports, but can't make conclusion for my problem. So I posed again. I have a problem with signal 11 and fault address. I checked stack message and the problem happened inside a recursive function ClassifyCase(). According to Stack frame #00, the error happened at cascadedetect.cpp:1394, that is recursive call of the ClassifyCase() function. Since calling to the ClassifyCase() didn't have problem in the earlier recursive call, I am sure ClassifyCase() doesn't have problem. That fault address happened at different places for different time of running the program. If so, what could be the problem and why I have fault address?

Is that running out of memory problem (memory not enough)?

The function is as follow:

void CascadeClassifier::ClassifyCase(Tree_m Subtree, float Weight, float *LowClassSum, float *ClassSum)
{
}

The message is as follow:

Answer 1

I see a SEGV-MAPERR. It could be related to out of memory, try adding large-heap to your manifest.
