Gpetr,

Well, you could give a few more details, for example :
- the GDAL version used
- what kind of raster (which GDAL driver) are you trying to open ?
- which GDAL command do you try: gdalinfo, gdal_translate ?
- type of CPU: Intel-like ? (bus error can happen more frequently on other 
hardware architectures such as Sparc)
- a link to the file you try to open or provide it as an attachment to a ticket 
to http://trac.osgeo.org/gdal/newticket
- if you have the gdb utility installed, a stacktrace of the GDAL utility when 
the bus error occurs (and/or the same with the valgrind utility)

Hum, well perhaps hard disk failure could give a crash in portion of code that 
don't properly check the return code of I/O operations. But difficult to know 
and fix without knowing where the crash occurs within GDAL.
