Dynamips hypervisor process has stopped, return code: -11

I am getting this error:
Dynamips hypervisor process has stopped, return code: -11
C3725 'Ghost': generic_nvram_extract_config: Unknown error -61605

This happens when s0/0 is configured on either R1 and R2 (configured similar to below) but not when I configure f0/0 on either router.
I did see the bug from 2018 about compiling the i386 version just wanted to check if that would still be a viable solution or if this is a different bug

Running GNS3 and dynamips on arch linux

Start by reproducing the crash with Serial0/0 configured between the two C3725 routers on Arch Linux, then inspect the Dynamips path around generic_nvram_extract_config and the -11 process exit. Done means the same topology runs without the hypervisor stopping and the reported error no longer occurs.
