makemkvcon causes segfaults in orc

in my gentoo-systems makemkvcon does not run anymore; on intel with 3.12.8-gentoo it causes segfaults in liborc:
Code: Select all
makemkvcon[22625]: segfault at 0 ip 00007f1aaa9e0002 sp 00007fffb2f3fcc8 error 4 in liborc-0.4.so.0.17.0[7f1aaa9e0000+79000]
and on amd with 3.13.0-gentoo-r1:
Code: Select all
makemkvcon[16446]: segfault at 7fc75df2c000 ip 00007fc75df2c000 sp 00007fff782f4d08 error 14 in zero[7fc75df30000+60000]
i've tested it with orc-0.4.16-r1; orc-0.4.17 and orc-0.4.18 (the current version installed by the package-manager)
all systems use glibc-2.18-r1 compiled with linux-headers 3.13.
what can i do to get makemkv up&running again?

Hello,
I think, it could ba a problem with glibc. The last time I converted some BD/DVDs at Jan. 17th with MakeMKV. If I start it today, makemkv crashes after about 30 seconds with a popup "Fehler aufgetreten, Programm wird beendet" in german, which means "Error occured, program gets terminated". makemkvcon -info iso:<filename> segfaults almost immedeately.
dmesg shows sth like:
Code: Select all
makemkvcon[7668]: segfault at 7f45ffc8d000 ip 00007f45ffc8d000 sp 00007fff444e5878 error 14
The main difference between the last working config and now is a upgrade of the glibc version from 2.17 to 2.18.
Regards,
Knut

Tried today with new version 1.8.8. Same error.
strace makemkvcon shows
Code: Select all
--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_ACCERR, si_addr=0x7f8ad9711000} ---

THX for the replies - i already suspected that.
i haven't tested the new version yet and i guess we will not get the source to compile makemkvcon ourselves.
i briefly thought about downgrading glibc but i really do not want to destroy some smoothly-running systems.
so i guess the only thing that's left is to set up and run makemkv from a chroot - a huge PITA.
i'll still check new makemkv-versions and keep you posted.

I'm seeing the same issue. Makemkv-1.8.9 fails in the same fashion.
[257989.137146] makemkvcon[25383]: segfault at 0 ip 00007f0dee729002 sp 00007f0dce783868 error 4 in liborc-0.4.so.0.18.0[7f0dee729000+7c000]

Just as a point of reference, 1.8.9 works for me with kernel 3.13.4-1 and libc 2.18-3 on debian. So it might be something else on your system.

nice for you, but no go on my boxes. i tried 1.8.7, 1.8.8 and 1.8.9; with stable and unstable. i downgraded liborc from 0.4.18 to 0.4.17 - the same results:
Code: Select all

the binary nvidia-driver (which causes a lot of troubles even in 3.12.8 now) is not the reason, either; above dmesg is from a system with nouveau.

Hmm... wonder where the difference lies as there is no love on my system - libc 2.18, kernel 3.13.5, orc 0.4.10, and makemkv crashes everytime (it used to run just fine). This is a 64 bit Gentoo box.

I have liborc 0.4.18-1, so that's a difference between our systems.

Typo on my part - I do have 0.4.18.

Are we getting anywhere on this bug? Any additional information needed in order to resolve?

I too, have the problem that makemkvcon segfaults.
The gentoo forums also have a topic about those problems, see
here.
If i can help with anything, just let me know. MakeMKV is a fantastic tool, and i would be happy to get it running for me again.
Thanks for your help!

Please send a core file of makemkvcon (see /onlinehelp/dump.html ) + binaries of all libraries loaded by makemkvcon (ldd makemkvcon). Thanks!

Taking this a step further; liborc is a dependency of the schroedinger/dirac codec. After completely removing liborc/libschroedinger, a segfault now occurs in libogg.
Code: Select all
$ makemkvcon stream 123.mpeg
kernel: makemkvcon[29751]: segfault at 0 ip 00007f30316ed002 sp 00007fff499897d8 error 4 in libogg.so.0.8.1[7f30316ed000+6000]
