Sadly you do not have debugging symbols enabled, so the backtrace is not really useful. Please see also https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports Created attachment 111866 [details]
backtrace.txt
I ran into this bug in Gentoo Linux after building amarok from git as of commit adcbef160f03dcd54c44e3f0ff7a5c1d3c198532 (4/4/2018). This is full gdb backtrace of all threads with symbols.
In my backtrace, the segfault happens in 'get_charset ()' in file
> ../source3/registry/reg_parse_internal.c
In the original submitted backtrace, the symbol is from "/usr/lib/libsmbconf.so.0".
Both of there reference the 'get_charset' symbol from samba even though, looking at the sourcecode, it seems mysql includes its own definition of 'get_charset' in the file "mysys/charset.c:. Is there something about the way amarok loads mysql that could cause it to bind to 'get_charset' from the wrong library?
Could you please not hijack a bug which was about a different version? FWIW: backtraces need to be posted as comments, attachments are not searchable unfortunately. And please do not confirm reports yourself, those need to be confirmed by the developers.

I'll opened a new bug https://bugs.kde.org/show_bug.cgi?id=392848 Backtrace with libsmbconf debug symbol, you can see: "#6 0x00007f4d74bf46da in get_charset (c=0xe0 <error: Cannot access memory at address 0xe0>) at ../source3/registry/reg_parse_internal.c:220" It's enought?

The library which is loaded first takes precedence, which is in this case libsmbconf through ffmpeg. If libmariadbd/libmysqld is loaded first, get_charset resolves to the right library. To force this, just LD_PRELOAD=/usr/lib64/libmariadbd.so.19 amarok makes it work fine here.

I don't have the means to test right now so I'm going to close this. |
