I'm running a system using the Linux 2.4.19-aa1
kernel without module support. pmcd dumps core after running in
ksyms.c. Specifically, it dumps core in the find_dup_name function on the
line:
res = strcmp(ksym_a[i].name,
name);
since ksym_a[i] is equal to 0x0. This
function is called from line 417:
/*
Determine if symbol is already in ksym
array.
If so, make sure the addresses match.
*/
res =
find_dup_name(ix - 1, addr, strbuf);
which is called from:
void
read_ksym_sources()
{
__psint_t
end_addr;
/* ...snip... */
if
(read_ksyms(&end_addr)) /* read /proc/ksyms first
*/
read_sysmap(end_addr); /*
then System.map */
}
I'm not sure how to fix this; checking for a null
is easy but fixing (and understanding) the cause is better. I have a
corefile available....
The reason I tried 2.3.0 is because many of my
systems are reporting no disk performance measurements (disk.*) at
all.
