I got a "No matching code found" when I use markup_oops.pl parse a error
in a x86_64 module.
cat e.c
int init_module(void)
{
char *buf = 0;
buf[0] = 3;
return 0;
}
void cleanup_module(void)
{
//char *buf = 0;
//buf[0] = 3;
}

0000000000000000 <init_module>:
init_module():
/home/teawater/study/kernel/stack2core/example/e.c:10
0: c6 04 25 00 00 00 00 movb $0x3,0x0
7: 03

13: 90 nop
Disassembly of section .modinfo:
This is because the faulting instruction "movb $0x3,0x0" is the first
line of the range.
In the markup_oops.pl:
main::(./scripts/markup_oops.pl:245):
245: if (InRange($1, $target)) {
DB<2> p $line
ffffffffa001b000: c6 04 25 00 00 00 00 movb $0x3,0x0
DB<3> p $counter
0
It just set $center in next loop. So it cannot get the $center.
And even if $center is set to the right value 0.
if ($center == 0) {
print "No matching code found \n";
exit;
}
The first line $center will be 0, so I change the default value to -1.
