Bug ID: 17039
Summary: malloc_info should use chunksize() for normal bins
stats too
Product: glibc
Version: 2.21
Status: NEW
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: jipan.yang at gmail dot com
CC: drepper.fsp at gmail dot com
Fast bin is using "size_t thissize = chunksize (p);".
Using r->size directly gives wrong total and avail size data.
if (r != NULL)
while (r != bin)
{
++sizes[NFASTBINS - 1 + i].count;
sizes[NFASTBINS - 1 + i].total += r->size;
sizes[NFASTBINS - 1 + i].from
= MIN (sizes[NFASTBINS - 1 + i].from, r->size);
sizes[NFASTBINS - 1 + i].to = MAX (sizes[NFASTBINS - 1 + i].to,
r->size);
r = r->fd;
}

Probably it'll be good to have top chunk data shown for each arena. Not sure
about last remainder since it is already in the unsorted bin.
