after a reboot, it works now. unmerge media-fonts/font-adobe-100dpi media-fonts/font-bh-lucidatypewriter-100dpi media-fonts/font-bh-lucidatypewriter-75dpi crash happyens again. so i think ddd is depend on these fonts packages.
found a way to avoid depend on any specific fonts, before first running , run $mkdir -p ~/.ddd/ $cat > ~/.ddd/init << EOT Ddd*defaultFont: * Ddd*variableWidthFont: * Ddd*fixedWidthFont: * Ddd*dataFont: * EOT

But yes, some bitmap fonts will need to be added to RDEPEND.

I installed these fonts listed, but the crash is still happening. This warning "using font "fixed" instead" did not appear on my system. It seems that the crash is also based on some other unknown conditions.So, is there anything else I can do for you?
Now that ddd-3.4.1 added support for TTF fonts via freetype, I think this problem should happen anymore.
As for a working dev-debug/ddd-3.4.1 here, I had to add both motif22-compatibility && xft as in: Installed versions: 2.3.8-r5(16:40:46 05/11/2024)(motif22-compatibility xft -examples -jpeg -png -static-libs -unicode ABI_MIPS="-n32 -n64 -o32" ABI_S390="-32 -64" ABI_X86="64 -32 -x32") Each have been tested unitary, unsuccessful.
