When I use markup_oops.pl parse a x8664 oops, I got:
objdump: --start-address: bad number: NaN
No matching code found
This is because:
main::(./m.pl:228): open(FILE, "objdump -dS --adjust-vma=$vmaoffset
--start-address=$decodestart --stop-address=$decodestop $filename |") || die
"Cannot start objdump";
DB<3> p $decodestart
NaN
This NaN is from:
main::(./m.pl:176): my $decodestart = Math::BigInt->from_hex("0x$target") -
Math::BigInt->from_hex("0x$func_offset");
DB<2> p $func_offset
0x175
There is already a "0x" in $func_offset, another 0x makes it a NaN.
The $func_offset is from line:
if ($line =~ /RIP: 0010:\[\<[0-9a-f]+\>\] \[\<[0-9a-f]+\>\]
([a-zA-Z0-9\_]+)\+(0x[0-9a-f]+)\/0x[a-f0-9]/) {
$function = $1;
$func_offset = $2;
}
I make a patch to change "(0x[0-9a-f]+)\/0x[a-f0-9]/)" to
"0x([0-9a-f]+)\/0x[a-f0-9]/)".
