Corrupted heap

[Vincent Richomme]

Hi,

I wanted to debug ProjectCenter and I started with gdb:

Reading symbols from
C:\Developer\Mingw-NG\GNUstep\System\Applications\ProjectCenter.app/./ProjectCenter.exe...done.
(gdb) r
Starting program:
C:\Developer\Mingw-NG\GNUstep\System\Applications\ProjectCenter.app/./ProjectCenter.exe
[New Thread 3144.0xf24]
warning: Can not parse XML library list; XML support was disabled at
compile time
warning: HEAP[ProjectCenter.exe]:
warning: Invalid Address specified to RtlFreeHeap( 003E0000, 004D005C )


Program received signal SIGTRAP, Trace/breakpoint trap.
0x7c91120f in ?? ()

First I thought it was because of the fact I was using msys/mingw and
everyone says
that it's not a very well supported environnment.
So I tried with my old Visual studio and I could see something similar :

ProjectCenter
------------------------------------------
HEAP[ProjectCenter.exe]: Invalid Address specified to RtlFreeHeap(
003E0000, 00760065 )
Windows has triggered a breakpoint in ProjectCenter.exe.
This may be due to a corruption of the heap, which indicates a bug in
ProjectCenter.exe or any of the DLLs it has loaded.
This may also be due to the user pressing F12 while ProjectCenter.exe has
focus.

I have also tested another application called Gorm and I have other kind
of errors :

The weird thing is the fact, applicationa are launched anyway when you are
not debugging them
ie you don't really notice them when launching.

So I think GNUstep on windows is not for the faint of heart ...
