[Csnd-dev] Segfault on RPi

Just doing my periodic pull and build (develop branch) on my RPi 5.
Build went fine (I did "make clean" and removed the CMake cache). After
installing and running ldconfig, I get this:

dave@phonon:~/src/csound/build $ csound
Malloc failed: memory allocate failure for 12963674408
Error in pre-initialisation function of module 'libsfont.so'
Failed during csoundLoadModules
Segmentation fault

I'm on bookworm (Linux 12), fully up to date.
