Android程序崩溃信号11和故障地址

Question

我搜索并发现了很多信号11报告，但无法对我的问题作出结论。所以我再次提出。信号11和故障地址有问题。我检查了堆栈消息，并且在递归函数ClassifyCase()内发生了问题。根据Stack frame #00，错误发生在cascadedetect.cpp:1394，即递归调用ClassifyCase()函数。 因为调用ClassifyCase（）在先前的递归调用中没有问题，所以我相信ClassifyCase（）没有问题。该故障地址在不同的时间运行该程序的不同地点发生。 如果是这样，可能是什么问题，为什么我有错误的地址？

是否内存不足问题（内存不够）？

功能是如下：

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

该消息是如下：

Answer 1

我看到SEGV-MAPERR。它可能与内存不足有关，请尝试将large-heap添加到清单中。
