No Terry there are no modifications from me to local files. I realy
don't know why the information is incomplete
but I didn't make any modifications.
Its possible that a memory problem cause this errors? Again, last
night the computer stop running 3 times without
an apparent cause. This afternoon the first time a turnned on the
computer it panics again with a fatal trap 12. I'll try
to change this memory just to eliminate the possibility of hardware
problem then if it continues i'll do a hard study on
gdb and try to find some info.
Could you provide some good source of information to gdb?
Thanks Diego
