After successfully building rrdtool 1.2.23 on AIX 5.3 with xlC v8 i
have the problem that rrdtool stay in the process list after issueing
the following rrdtool sub command:

truss /usr/bin/rrdtool graph --start 1194882493 --end 1194886093 --
width 300 --height 75 \
--title weight --color BACK#ffffff \
- DEF:sum="/ganglia/rrds/p690/node1/
weight.rrd:sum:AVERAGE" \
AREA:sum#0000ff:"node1 last hour (now -1.00)"

.......
sigprocmask(0, 0x00000000, 0x2000C2D4) = 0
close(3) = 0
_fp_fpscrx_sc(0x00000002, 0xA0000100, 0x0000000C, 0xD0D5C3A8,
0x00000000, 0x0000006B, 0xF0F768B8, 0x00000011) = 0xA0000100

The process does not continue. Does somebody knows what this
_fp_fpscrx_sc means ?
