Dear Maintainer,
I tried to find out where this stack in message #25
would point to, if it may help.
The failing call to free, I guess, would be in
function rotateLogSet in logrotate.c, line 1749.
1748 for (i = 0; i < log->numFiles; i++) {
1749 free(rotNames[i]->firstRotated); <<<<
1750 free(rotNames[i]->disposeName);
1751 free(rotNames[i]->finalName);
1752 free(rotNames[i]->dirName);
1753 free(rotNames[i]->baseName);
1754 free(rotNames[i]);
1755 }
Kind regards,
Bernhard
