you did this much debugging work, maybe you could also assign the bug. :/
(In reply to Alex Xu (Hello71) from comment #1) > you did this much debugging work, maybe you could also assign the bug. :/ Apologies! I think I still had “leave bug-assigning to the bug-wranglers” in the back of my mind, though I'm not sure where it came from in the first place. Thank you!
Is this segfault still happening with recent glibc?
Talk about a bug I forgot about... I had to switch to a different keyboard, but the G15 I still have works enough to test this out, and indeed, the segfault is still there, though it actually gives a backtrace now without GDB.

@Andreas K. Hüttel I can confirm and reproduce the Bug. But perhaps as Workaround: (as described above) add "dev-libs/libg15render -truetype" to your "/etc/portage/package.use/<MYFILE>.use" and rekompile lig15render It works now... :-) Hopefully the bug will be fixed in near future...
