Android程序崩潰信號11和故障地址

Question

我搜索並發現了很多信號11報告，但無法對我的問題作出結論。所以我再次提出。信號11和故障地址有問題。我檢查了堆棧消息，並且在遞歸函數ClassifyCase()內發生了問題。根據Stack frame #00，錯誤發生在cascadedetect.cpp:1394，即遞歸調用ClassifyCase()函數。 因爲調用ClassifyCase（）在先前的遞歸調用中沒有問題，所以我相信ClassifyCase（）沒有問題。該故障地址在不同的時間運行該程序的不同地點發生。 如果是這樣，可能是什麼問題，爲什麼我有錯誤的地址？

是否內存不足問題（內存不夠）？

功能是如下：

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

該消息是如下：

Answer 1

我看到SEGV-MAPERR。它可能與內存不足有關，請嘗試將large-heap添加到清單中。
