mkvmerge segmentation fault

Hello
What might be the reason for mkvmerge generating segmentation fault every time
I try to use it?
First I compiled "libebml-0.7.6", "libmatroska-0.8.0", and "mkvtoolnix-1.6.5"
without any additional components or gui. All went fine and after
"make install" I got the help page when I run mkvmerge. If I try to
give it any input file, even when using the example file from
matroska page: "mkvmerge -i mewmew-vorbis-ssa.mkv"
Always same thing "segmentation fault".
Then I tried to install it from the RPM binary package "mkvtoolnix-1.6.5-1.i386.rpm",
it needed flac lib and some tweaks to run but finally it did the same thing, shows the
help page without parameters and segmentation fault with any input.
Now I tried to compile again with --enable-debug, still help page comes out fine
but any input gives this time "Illegal instruction".
I included the output of gdb with bt here:
Strange that it complains of not finding any debug symbols even if I compiled it
with --enable-debug.

I also run it with : strace mkvmerge -i mewmew-vorbis-ssa.mkv
It produced lots of text so here is only the last page:
