Re: [Gdcm2] Buffer problem in Qt environment

[Sylvain A. <syl...@ho...>]

Okay. Nevermind for the main page, must be my proxy or something.

Concerning the bug, well, it does only appear with the line 3 in this:

========================
1.    buffer = new char[gimage.GetBufferLength()];
2.    
3.    gimage.GetBuffer(buffer);
========================

It does NOT appear when I comment the line 3. It only says

-----------------------------------------
HEAP[MyProgram.exe]: 
Invalid Address specified to RtlFreeHeap( 05080000, 04DAA558 )
-----------------------------------------

This is displayed when I'm debugging. But the program works perfectly, and no critical errors are found. Looks to me there's something in that line that affects my compiler (mingw32-make, which is packed with Qt Creator, the IDE I'm using).

I guess this kinda problem vanishes when you compile in "release" mode. I just wanted to let you know.
