Hello,
i compiled rrdtool on aix 7.1 with gcc. I run rrdtool dump in order check the files gmond generated.
That command generates a core file. Truss shows me the following system calls:
23986386: 23658713: __loadx(0x01480080, 0x2FF21370, 0x00000A50, 0x2FF21ED0, 0x00000000) = 0xD0542128

23986386: 23658713: kwrite(1, " < r r d >\n", 6) = 6
23986386: 23658713: kwrite(1, "\t < v e r s i o n > 0 0".., 25) = 25
23986386: 23658713: kwrite(1, "\t < s t e p > 1 5 < / s".., 34) = 34
