fpe_shader.c Segfault on RPI4/arm64

Open Algebro7 opened this issue 4 years ago • 0 comments
I've been using gl4es for awhile now on my 32 bit odroid XU4 for stepmania, and it has always worked great. I just got an RPI4 and installed the AARCH64 version of Arch Linux ARM on it and I'm getting the following crash on fpe_shader.c:482:
$ LD_PRELOAD=./libGL.so.1 LIBGL_ES=2 LIBGL_GL=2 gdb ./stepmania-release-symbols

gl4es was built with the odroid profile per the COMPILE instructions.
Oddly enough, if I run it on v1.1.0 of gl4es, the game launches without the segfault but freezes later on when navigating the menus. The game runs normally without gl4es (although the performance is quite bad), and it runs great on my XU4, so I'm wondering if ARM64 and/or the RPI4 are causing problems with gl4es. Any ideas on how to troubleshoot?
