1. Could you provide a minimal example that triggers the segfault? 2. Have you actually enabled USE=24-bit-color or not? Come to think of it, please show us your whole 'equery u x11-terms/rxvt-unicode'

It doesn't matter - crashes in any case [ Legend : U - final flag setting for installation] [ : I - package is installed with flag ] [ Colors : set, unset ] * Found these USE flags for x11-terms/rxvt-unicode-9.22-r4: U I + + 24-bit-color : Enable 24-bit color support. Note that this feature is unofficial, may cause visual glitches due to the fact there is no termcap/terminfo definition for rxvt-unicode-24bit yet so it is necessary to use the one for 256 colours, visibly increases memory usage, and might slow urxvt down dramatically when more than six fonts are in use in a terminal instance. + + 256-color : Enable 256 color support - - blink : Enable blinking text - - fading-colors : Enable colors fading when off focus + + font-styles : Enable support for bold and italic fonts - - gdk-pixbuf : Enable transparency support using x11-libs/gdk-pixbuf - - iso14755 : Enable ISO-14755 support + + mousewheel : Enable scrolling via mouse wheel or buttons 4 and 5 + + perl : Enable perl script support. You can still disable this at runtime with -pe "" - - startup-notification : Enable application startup event feedback mechanism + + unicode3 : Use 21 instead of 16 bits to represent unicode characters + + utmp : Enable utmp support + + wtmp : Enable wtmp support + + xft : Build with support for XFT font renderer (x11-libs/libXft) It's very clear something is not okay with that "-= TOTAL_COLORS". What is that TOTAL_COLORS about? Anyway..
Could you try again with -r5, please? Both with and without USE=24-bit-color, turns out there was a bug in the patch used by -r4 which caused 24-colour to be enabled even when configure is called with --disable-24-bit-color.
Tried with both cases (with and without USE flag). Works for me.
Excellent, thanks for having reported this and your help with debugging!
