[Marble-bugs] Marble-0.8.0 crashes on tile load

[Algirdas Mockus]

Hello,

I compiled Marble-0.8.0 on Windws with MinGW 3.4.5 for Qt 4.5.3. I try to
run it on Win XP Sp3.
On development machine it runs fine. Bu if I move app to other XP machines,
it crashes when loading tiles (seems *division by zero*). The same thing
happens eith release and debug versions.

*Here's what GDB shows:*

...

*Program received signal SIGFPE, Arithmetic exception.
0x706b719e in Marble::AbstractScanlineTextureMapper::nextTile ()
   from Z:\release\libmarblewidget.dll*
(gdb)

------------------------------------------------------------------------------------------------------------

this was release version. If I run debug version, I get more exact info:

problem is in file "AbstractScanlineTextureMapper.cpp" in line 473.

   470: // tileCol counts the tile columns left from the current tile.
   471: // tileRow counts the tile rows on the top from the current tile.
   472:
  * 473: int tileCol = lon / m_tileLoader->tileWidth();*
   474: int tileRow = lat / m_tileLoader->tileHeight();

WHY DOES THIS HAPPEN ONLY ON OTHER XP MACHINES? As I mentoined on
development machine everything works fine.
