I have tried versions 5.2.47, 5.2.47-r1 and 6.0.6 from bug #482156 and all of them crashes with segfaults with backtrace ending with lines like /lib64/libc.so.6(__libc_start_main+0xf5)[0x7ff0c464ec05] Problems started today or yesterday - on Saturday everything was running well on version 5.2.47-r1, so probably some dependency got updates in the meantime but I couldn't figure out which. I can easily provide any details asked from any version of workbench, but need to know what could be useful.

Ok, I have the solution (inspired by https://bugs.gentoo.org/show_bug.cgi?id=482156#c33 ): emerge -aC antlr-c emerge mysql-workbench #any version that doesn't use system antlr So finally it comes down to some bug in antlr.

Seems like it. A possible cause was uncovered while adding mysql-workbench 6.0.7, so you could try that version as well since it uses the bundled version again.
