[Pkg-xfce-devel] Bug#440858: xfce4-sensors-plugin: sensors-plugin using 1/2GB after 21 days

[xsdg]

Package: xfce4-sensors-plugin
Followup-For: Bug #440858

I started three instances of xfce-sensors-plugin on Feb 5, 2008.  This is what
top says currently:
 2677 xsdg      15   0  184m  85m 2304 S    0  1.1   0:01.11 xfce4-sensors-p    
 2678 xsdg      16   0  521m 422m 2192 S    0  5.3   0:04.20 xfce4-sensors-p    
 2679 xsdg      15   0  511m 409m 2240 S    0  5.1   0:06.35 xfce4-sensors-p    

The first has been idle (displaying "Sensors"), whereas the second two have
been showing three measurements each (one of them updating every minute, the
other every 10 seconds).  Notably, I find the following in /proc/2678/smaps:
0060b000-1a986000 rw-p 0060b000 00:00 0                                  [heap]

Private_Clean:         0 kB
Private_Dirty:    429472 kB
Referenced:       429472 kB

The identical section for 2677 is:
0060b000-05a6f000 rw-p 0060b000 00:00 0                                  [heap]
Size:              86416 kB
Rss:               86348 kB
Shared_Clean:          0 kB
Shared_Dirty:          0 kB
Private_Clean:         0 kB
Private_Dirty:     86348 kB
Referenced:        86348 kB

This clearly suggests that pointers are being malloc()ed that aren't being
free()d.  Also, in case it's useful, here's an excerpt from /proc/2788/status:
VmPeak:   533860 kB
VmSize:   533856 kB
VmLck:         0 kB
VmHWM:    433736 kB
VmRSS:    432456 kB

VmStk:        88 kB
VmExe:        44 kB
VmLib:     12180 kB
VmPTE:      1052 kB

This was against xfce4-sensors-plugin 0.10.99.2-1, though since nothing appears
in the changelog about this leak, I presume it still exists in the latest
packaged version.
