Android位图致命信号11（SIGSEGV）

我正在开发和Android应用程序拍照并OCR它。
我有时和某个没有得到这个错误不改变我的代码，Android位图致命信号11（SIGSEGV）

出现错误：01-08 20:41:59.940: A/libc(10967): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1)

我有裁剪图像，让用户突出显示文本的方法：

private void performCrop(){ 

    File file = new File(_path); 
    Uri outputFileUri = Uri.fromFile(file); 

    try{ 

     //call the standard crop action intent (the user device may not support it) 
     Intent cropIntent = new Intent("com.android.camera.action.CROP"); 
     cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri); 
     //indicate image type and Uri 
     cropIntent.setDataAndType(picUri, "image/*"); 
     //set crop properties 
     cropIntent.putExtra("crop", "true"); 
     //indicate aspect of desired crop 
     cropIntent.putExtra("aspectX", 5); 
     cropIntent.putExtra("aspectY", 1); 
     //indicate output X and Y 
     cropIntent.putExtra("outputX", 500); 
     cropIntent.putExtra("outputY", 100); 
     //retrieve data on return 
     cropIntent.putExtra("return-data", true); 
     //start the activity - we handle returning in onActivityResult 
     startActivityForResult(cropIntent, 2); 

    }catch(ActivityNotFoundException anfe){ 
     //display an error message 
     String errorMessage = "Whoops - your device doesn't support the crop action!"; 
     Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT); 
     toast.show(); 
    } catch (Exception ex) { 
     Log.v(TAG, ex.toString()); 
    } 
}

这里是做方法OCR：

protected void onPhotoTaken() { 
    _taken = true; 

    BitmapFactory.Options options = new BitmapFactory.Options(); 
    options.inSampleSize = 2; 

    Bitmap bitmap = BitmapFactory.decodeFile(_path, options); 

    try { 
     ExifInterface exif = new ExifInterface(_path); 
     int exifOrientation = exif.getAttributeInt(
       ExifInterface.TAG_ORIENTATION, 
       ExifInterface.ORIENTATION_NORMAL); 

     Log.v(TAG, "Orient: " + exifOrientation); 

     int rotate = 0; 

     switch (exifOrientation) { 
     case ExifInterface.ORIENTATION_ROTATE_90: 
      rotate = 90; 
      break; 
     case ExifInterface.ORIENTATION_ROTATE_180: 
      rotate = 180; 
      break; 
     case ExifInterface.ORIENTATION_ROTATE_270: 
      rotate = 270; 
      break; 
     } 

     Log.v(TAG, "Rotation: " + rotate); 

     if (rotate != 0) { 

      // Getting width & height of the given image. 
      int w = bitmap.getWidth(); 
      int h = bitmap.getHeight(); 

      // Setting pre rotate 
      Matrix mtx = new Matrix(); 
      mtx.preRotate(rotate); 

      // Rotating Bitmap 
      bitmap = Bitmap.createBitmap(bitmap, 0, 0, w, h, mtx, false); 
     } 

     // Convert to ARGB_8888, required by tess 
     bitmap = bitmap.copy(Bitmap.Config.ARGB_8888, true); 

    } catch (IOException e) { 
     Log.e(TAG, "Couldn't correct orientation: " + e.toString()); 
    } 

    // _image.setImageBitmap(bitmap); 

    Log.v(TAG, "Before baseApi"); 

    TessBaseAPI baseApi = new TessBaseAPI(); 
    baseApi.setDebug(true); 
    baseApi.init(DATA_PATH, lang); 
    baseApi.setImage(bitmap); 

    String recognizedText = baseApi.getUTF8Text(); 

    baseApi.end(); 

    // You now have the text in recognizedText var, you can do anything with it. 
    // We will display a stripped out trimmed alpha-numeric version of it (if lang is eng) 
    // so that garbage doesn't make it to the display. 

    Log.v(TAG, "OCRED TEXT: " + recognizedText); 

    if (lang.equalsIgnoreCase("eng")) { 
     recognizedText = recognizedText.replaceAll("[^a-zA-Z0-9]+", " "); 
    } 

    recognizedText = recognizedText.trim(); 

    if (recognizedText.length() != 0) { 
     _field.setText(_field.getText().toString().length() == 0 ? recognizedText : _field.getText() + " " + recognizedText); 
     _field.setSelection(_field.getText().toString().length()); 
    } 

    // Cycle done. 
}
