Hi,
I am running root v2_00_05 on Linux. I am compiling my code.
The following loop causes the image size to grow and grow until the
machine is swamped (up to 80 MBytes!). I can't see the leak. Help!
Chris
PS I did try to delete dir1 and dir2, which caused immediate core dump.
I have commented out those statments. I understand that
h20 = (TH1C*)dir2->Get(histName);
causes a histogram object to get created in memory, and I must delete it.
But why then should
delete dir1;
cause a core dump?
Thanks.
for( card=0 ; card<16 ; card++ ) {
printf("Working on crate %d, card %d.\n",crate,card);
for( channel=0 ; channel<32 ; channel++ ) {
sprintf(dirName1,"Crate %d",crate);
sprintf(dirName2,"Card %d",card);
sprintf(histName,"Cr %2d. Ca %2d. Ch %2d. Ped corrected, uncut IHL",
crate,card,channel);
fDAQ20->cd();
dir1 = (TDirectory*)fDAQ20->Get(dirName1);
dir1->cd();
dir2 = (TDirectory*)dir1->Get(dirName2);
dir2->cd();
h20 = (TH1C*)dir2->Get(histName);
// delete dir1;
// delete dir2;
fDAQ16->cd();
dir1 = (TDirectory*)fDAQ16->Get(dirName1);
dir1->cd();
dir2 = (TDirectory*)dir1->Get(dirName2);
