g++ - Why gcc 4.1 + gcov reports 100% branch coverage and newer (4.4, 4.6, 4.8) reports 50% for "p = new class;" line? -

-

जब gcc 4.1 (जीसीओवी का उपयोग करके) अगली पंक्ति:

p = नया वर्ग;

को 100% शाखा कवरेज के रूप में रिपोर्ट किया गया है & lt; - यह मेरे लिए ठीक है।

जीसीसी 4.4 और उसके बाद के संस्करण का उपयोग क्यों किया जाता है:

[+ -] पी = नया वर्ग; (50% शाखा कवरेज) ... & lt; - यह 100% को कवर करने के लिए एक समस्या है!

जीसीसी के रूप में उसी शाखा कवरेज की रिपोर्ट करने के लिए क्या मैं नए जीसीसी संस्करणों के लिए कोई अतिरिक्त विकल्प सेट कर सकता हूं? 4.1 के रूप में एकल लाइनों के लिए "p = new class;"।

अग्रिम धन्यवाद।

हल!

हमारे पास कुछ सी / सी ++ फ़ाइलें हैं और बिना किसी अपवाद से निपटने के लिए, इसलिए प्रत्येक कोड ब्लॉक के लिए एलसीओवी / जीसीओवी प्रक्रिया "अपवाद प्रबंधन" है।

सामान्य ब्लॉक के अंदर , उदाहरण के लिए: 

  int main (शून्य) {... ... ... [+ -] printf ("हैलो \ n"); ...}   
 जीसीओवी रिपोर्ट बताती है कि प्रिंटफ़ लाइन में 50% का "शाखा कवरेज" है - & gt; क्यों?  
 क्योंकि अपवाद हैंडलिंग सक्षम है !!!  
 इस समस्या को हल करने के लिए, निर्दिष्ट करें:  
 
 -fno-exceptions   
 जी ++ कमांड लाइन में।  
 उदाहरण:  
 
 जी ++ -O0 --coverage -fno-exceptions -fno-inline ....   
 धन्यवाद!

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...

python - Writing Greek in matplotlib labels, titles -

I'm trying to write some text for labels, shape titles etc. with my plots, but no benefit till now Has not happened . I do not want to print specific characters (I know how to use special characters), I want to write the entire text in Greek (maybe Unicode and text ' ?). , suggesting that I would like to mention that for some reason I can not get matplotlib to cooperate with Tex (using IPython notebook from Anaconda in Ubuntu 14.10) so that there really is an option Will not be the first. I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??
