[rrd-users] librrd / rrd_graph / getenv

[Sole Caneiro]

 Hello to everybody!
 
 I'm trying to use librrd from a C main program. Execution fails sometimes when calling to rrd_graph(). The output of the debugger "Valgrind" is:
    
      ==31745==  Invalid read of size 2
     ==31745==     at 0x40CEBA3: getenv (in /lib/tls/libc-2.3.6.so)
     ==31745==    by 0x4125690: (within /lib/tls/libc-2.3.6.so)
     ==31745==    by 0x412635D: tzset (in /lib/tls/libc-2.3.6.so)
     ==31745==    by 0x402FD19: rrd_graph_init (rrd_graph.c:2875)
     ==31745==    by 0x40355AC: rrd_graph (rrd_graph.c:2801)
     ==31745==    by 0x8049B6C: main (in/home/sole/proyecto/erlang/lib/rrdtool_app-1.0/priv/ExtProg)
     ==31745==  Address 0x4115006B is not stack'd, malloc'd or (recently) free'd
     ==31745==
     ==31745==  Process terminating with default action of  signal 11 (SIGSEGV)
    
  Could you help me to solve this problem?
  
    Thanks in advance!
  Sole.
