Package: memtest86+
Version: 5.01-2
Severity: normal
Dear Maintainer,
I am using memtest86+ to test the memory of an old Pentium 4 PC.
memtest86+ reports errors (which I believe are real RAM errors).
However, in the error list or in the error summary, the translation
from the address into a 'MB' representation seems strange:
I have not kept track of the report with detailed memory, but I wrote down
the strange message in error summary mode.
the output indicates (copied manually but checked several times
and I have also a photo just to be sure :).
Lowest Error Address: 00040d0fe8c - 1037.9MB
Highest Error Address: 00040d1bedc - 1037.6MB
What is strange is that the highest error address is
'less' MB than the lowest error address : the lowest
address is shown as 1037.9, and the highest as 1037.6
I am expecting to have the highest error address be 'equal more MB'
than the lowest address.
It is also not very clear how the address is translated in MB.
E.g. this is what I obtain when I am dividing by (1024 * 1024.0)
(gdb) p 0x00040d0fe8c / (1024 * 1024.0)
$1 = 1037.0621452331543
(gdb) p 0x00040d1bedc / (1024 * 1024.0)
$2 = 1037.1090965270996
(gdb)
At least the nrs given by the above gdb commands are logical.
I hope I have given all the relevant info.
Thanks
Philippe
