After about 1 minute and 40 seconds, appears to be done processing a.txt and b.txt. But still the endless loop afterwards.
Bug not fixed yet.

ooops!
you are right.
5th time run this app, I saw the bug.
it must be a randam bug.

the result c and d is correct.
thread 1 and 2 already quit. but checkQuit is failed.
I must made a mistake on the check thread proc.

It surely happened here though. Windows 7 if that makes any difference. Over 30 minutes and the program never finished, kept repeating what is shown in the screenshot above.

What exactly are you trying to do? "shellcode"?
I don't know what either .rodata and mprotect() are... elaborate, please.

This??? mprotect() that is...

need your testFiles to find the bug

They are your files... (exactly the a.txt and b.txt from the 3 part download) and the latest version of your program. Or do you mean c.txt and d.txt?

The last time I ran the program, it is still stuck in the endless loop after 15 minutes still running in that loop.

Edit to add...about 20 minutes after this was first posted...
Now still running after 30+ minutes.... I think it's time to put it to bed.

Seems to be working ..... but
there also seems to be an endless loop, where the processing is already done -- but the program keeps "going to check whether all threads quit" etc... (endlessly see screenshot)



I stopped the program after 7 minutes while it was still stuck in the loop.

There also seems to be a couple of stalls along the way, where the program does not do anything for several seconds.
