Not related to Release Engineering, throwing back to Wranglers.
so the issue is ivtv-detect is segfaulting. However, honestly at this point I would need you to include emerge info just like every other bug report requires. Also I need the output of ls -l /lib/modules/`uname -r`/kernel/drivers/media/video/
Also run it through gdb and include a backtrace

Found a link to this problem. Have to use google cache since ivtv's trac is down. http://64.233.167.104/search?q=cache:cG3t88TBYz0J:ivtvdriver.org/trac/ticket/47+ivtv-detect+segmentation+fault&hl=en An IRC chat revealed this: [12:38] <jd86> now, why does ivtv-detect seg fault. [12:40] <jd86> oh my alot of things are seg faulting [12:41] <laga> that's not a good sign [12:43] <jd86> nope [12:43] <laga> probably broken memory, you could try memtest86 to check it Could be a possiblity in my case. I'm using a bunch of scrap parts I found laying around. I'll run memtest86 and let you know what happpens.
Could be a solution here! http://www.livejournal.com/community/gentoo/252562.html See the very bottom of the page: "I had the same problem and tracked it down to an assumption in ivtv-detect.c that there would only be 15 devices. In /dev I actually has 64 video devices, so ivtv-detect was getting an array overrun. On line 35 in ivtv-detect,c it says:" #define MAXDEV 15 "I increased it to 64, recompiled, and it worked. An alternative to this is to install udev, but that may not be such a good thing because udev doesn't automatically create the /dev/video* devices." "I hope this helps."
Solution described in Comment #8 works for me. ivtv-detect works perfect now.
Created attachment 74011 [details, diff] New ebuild for that includes patch for this bug
Created attachment 74012 [details, diff] Actual patch to ivtv-0.4.0 to solve this bug
Hi All, I -also- encountered this bug, so i made a local patch to solve it. This is my first try to make a new ebuild and I have no clue what's the best way to proceed (I made the new version number,0.4.0-r3, up myself) but it works after storing these files in media-tv/ivtv (and media-tv/ivtv/files) and doing a ebuild ... digest. So maybe someone with more gentoo-karma can put this into portage for others and close this bug?
