I'm the maintainer of the makemkv packages for gentoo and several users are complaining of segfaults with the following error:

makemkvcon[24345]: segfault at 0 ip 00007fcb08f36002 sp 00007fcae8f90868 error 4 in libfftw3f.so.3.3.2[7fcb08f36000+16e000]

I have not been able to duplicate it yet myself.

Seeing this issue on gentoo. We don't have a single version of ffmpeg/libav libraries - if there is incompatibility with specific versions and a patch is required, we need to update our packages to detect and apply if makemkv source doesn't handle it. #define LIBAVCODEC_VERSION_MAJOR 54 #define LIBA...

Testing possible fix....looks like filtering all -O flags except for -Os was the right path

Testing a possible fix -- more details at: https://bugs.gentoo.org/show_bug.cgi?id=439380

More info-- Using default gentoo cflags for 1.8.0 doesn't work(no output/hang), but if all flags but -Os are filtered, than the message "application failed to initialize" is received. Debug info: matt@hyperion ~/.MakeMKV $ makemkvcon info disc:0 [1]+ Exit 1 makemkv Segmentation fault matt@...

This problem still occurs with 1.8.0 .....seems to have been that way since 1.7.8 at least. No debug output, just two processes - makemkv and gui server, with one using all cpu, no output sent to console or any logfiles that I can see.

I've bumped makemkv on gentoo to 1.7.8 -- we'll hold off on pushing 1.7.9 until there is a better idea what is breaking with it. I noticed the changelog has a reference to glibc changes in 1.7.9....may need to go look into what that entailed. Gentoo users can be running anything from glibc 2.10 to 2...
