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]/)".
