makemkv immediately segfaults on both 14.1 and current (multilib)

I'm trying to get makemkv from Slackbuilds to work on a multilib system. It builds fine, both on 14.1 as well as on current. However on running it triggers an immediate segmentation fault on both 14.1 and current. Below a stacktrace from 14.1, which seems to point to libQtGui as the culprit?

Anyone any suggestions on how to get makemkv to run and/or further debug this?

Code:
hge@pulsar:~$ makemkv

I have no idea if this is the problem or not, but someone else reported that makemkv was failing on their system (but not on a clean VM) when compiled with -fPIC. This may be completely unrelated but can you try the following patch to the SlackBuild?
Code:
--- makemkv.SlackBuild.orig	2015-01-11 12:58:29.551420736 -0500
+++ makemkv.SlackBuild	2015-01-11 12:58:49.042066125 -0500
@@ -86,8 +86,6 @@
  \( -perm 666 -o -perm 664 -o -perm 640 -o -perm 600 -o -perm 444 \
   -o -perm 440 -o -perm 400 \) -exec chmod 644 {} \;
 
-CFLAGS="$SLKCFLAGS" \
-CXXFLAGS="$SLKCFLAGS" \
 ./configure \
   --prefix=/usr \
   --libdir=/usr/lib${LIBDIRSUFFIX} \
If it works, even though I'm not able to reproduce it here, I may just drop the CFLAGS and let makemkv's configure script figure it out, even though it should work fine as is (and does for me).

If that *doesn't* help, then I'm really not sure what the problem is. The output of the following commands may help:
Code:
$ ldd /usr/bin/makemkv
$ file /usr/bin/makemkv
Is this a full Slackware installation?

@T3slider:

1) Yes removing the setting of the CFLAGS and CXXFLAGS from the script removes the segfault. Weird but true. Thanks!

2) This is a stripped minimal install using the 3.12 kernel, but that in itself wouldn't explain a segfault. If I compared the config logs with and without the standard CFLAGS and CXXFLAGS there are more changes then just -FPIC. At several places the O2 optimization is removed and the g option to keep symbol information gets added. Complete diff for the config lows below in case it provides any insight.

The libraries (libdriveio.so, libmmbd.so and libmakemkv.so) have -fPIC hard-coded in the Makefile (as they should) but I'm guessing there is some symbol overlap or something similarly odd with the main makemkv binary so it's probably easiest just to compile it without -fPIC. So I'll update the SlackBuild within a few days, since I believe it segfaults on -current even if it works fine on a stock 14.1 install.

I had tried it on a pretty clean current + multilib install before posting and there it indeed also segfaults.

Doesn't get much simpler.
Code:

Thanks, willysr.

[edit] On second thought, that should really be tested -- it could also be the O2 optimization that's breaking it. Not being able to reproduce the segfault here, I can't test it myself; if someone who *did* experience the crash could test the above patch and confirm if it works or not, that would be great. If it still doesn't work then CFLAGS/CXXFLAGS should just be scrapped entirely (for x86 and x86_64), which would look like this:

I just edited the SlackBuild manually and removed -fPIC, so this is what I have now:

Code:
if [ "$ARCH" = "i486" ]; then
  SLKCFLAGS="-O2 -march=i486 -mtune=i686"
  ARCHDIR=i386
  LIBDIRSUFFIX=""
elif [ "$ARCH" = "i686" ]; then
  SLKCFLAGS="-O2 -march=i686 -mtune=i686"
  ARCHDIR=i386
  LIBDIRSUFFIX=""
elif [ "$ARCH" = "x86_64" ]; then
  SLKCFLAGS="-O2"
  ARCHDIR=amd64
  LIBDIRSUFFIX="64"
else
  SLKCFLAGS="-O2"
  ARCHDIR=i386
  LIBDIRSUFFIX=""
fi

Great, thanks. So that first patch from my last post should be sufficient.
