#31 Unable to set track number

[Anonymous]

Any attempt to set a track number results in a
Segmentation fault. Setting other tags works fine, and
if I set the track number using another program I can
view it with id3v2. Unfortunately this prevents the
program from being useful to me; a fix would be greatly
appreciated.

I've had no problems setting the track number.

But, I am suspicious of the accuracy of id3v2. I've used
other apps to set some of the fields, and, oddly enough, the
track number is *not* showing up via id3v2 if the track
number is set with another application.

I too have had this same problem. It doesn't let me set the track as well as it does not let seem to read the track information correctly.

I _had_ this problem, and sniffed around in the source to locate the exact issue, and found a fix which both eliminates the segmentation fault, and also, in my case at least, sets the track no.

The fix is to change the file id3v2.cpp around line no 431 to read:

// the track number for this file. In this case combine them.
char *currentTrackNum, *newTrackNum;
newTrackNum= NULL; // Add this one to properly set it to a NULL value
... // keep lines inbetween here
myFrame->Field(ID3FN_TEXT) = frameList[ii].data;
myTag.AttachFrame(myFrame);

if (newTrackNum != NULL)
{
free(newTrackNum);
}
break;
... // Add the if-clause around the free()-statement, which is the one failing...

Hope this helps!

This problem has just reared its head for me too. There was no problem with an earlier system of mine, but now with Slackware 12.0 I get this:
