On my Raspberry Pi 2, I observed that VDR 2.6.9 (with the rpihddevice plugin) would hit SIGSEGV due to dereferencing a null pointer:

#0 __GI_strlen () at ../sysdeps/arm/armv6/strlen.S:26 #1 0x76a9b434 in __GI___strdup (s=0x0) at strdup.c:41 #2 0x000ff354 in cRecording::cRecording (this=0x196cab0, FileName=0x0) at recording.c:919 #3 0x00100978 in cRecordings::DelByName (this=this@entry=0x1dd13c cRecordings::recordings, FileName=0x0) at recording.c:1699 #4 0x000d92f8 in cMenuRecordings::Delete (this=0x17bf200) at tools.h:188 #5 0x000e755c in cOsdMenu::ProcessKey (this=this@entry=0x1963be8, Key=Key@entry=kYellow) at osdbase.c:535 #6 0x000d640c in cMenuMain::ProcessKey (this=0x1963be8, Key=kYellow) at menu.c:4606 #7 0x000749a0 in main (argc=<optimized out>, argv=<optimized out>) at vdr.c:1419

To reproduce: 1. Start cutting a recording "name" (DVB-T2, H.264 in my case). 2. Delete the original recording. 3. Attempt to delete "%name", which still appears in the menu.

Note: At the time of the crash, an empty subdirectory "%name" will exist.

Because I am not familiar with this part of the code and I don't think that https://rr-project.org would work in this environment, I did not try to find the exact root cause or try to develop a fix. I assume that cCutter would have removed the "%name/2024-08-*.rec" directory as soon as it noticed that the "name" recording had disappeared. It failed to remove "%name" or the corresponding Recordings menu entry.

Best regards,

Marko
