| |
Hello,
When I try to use markup_oops.pl in x86, I always get: cat 1 | perl markup_oops.pl ./vmlinux objdump: --start-address: bad number: NaN No matching code found This is because in line: if ($line =~ /EIP is at ([a-zA-Z0-9\_]+)\+0x([0-9a-f]+)\/[a-f0-9]/) { $function = $1; $func_offset = $2; } $func_offset will get a number like "0x2" But in follow code: my $decodestart = Math::BigInt->from_hex("0x$target") - Math::BigInt->from_hex("0x$func_offset"); It add other ox to ox2. Then this value will be set to NaN.
So I make a small patch to fix it.
Best regards, Hui
