tuxmath from repository openSUSE:Eductaion crashes on startup. The crash is in
0x00007ffff796a09f in __rawmemchr_avx2 () from /lib64/libc.so.6. I have tried
to debug tuxmath but it is not possible to build tuxmath, as the header files
installed from t4k_common-devel are wrong/incompatible with tuxmath. There are
undefined symbols upon complilation (see below).
