[rrd-users] rrdtool[2489]: segfault while creating grafic

[Tobias Oetiker]

Hi Thomas,

I tried your example and on rrdtool 1.4.3 and rrdtool-trunk it does
not crash ...

I also ran it with valgrind and it see no problem :-(

can you try valgrind on your machine ?

valgrind --leak-check=full rrdtool graph ...

it will find some 'leaks' especially in font-config/pango code, but
this is fine ...
