Buffer overflow when built on Ubuntu 24.04 x86_64 #811

Open ExplodingLemur opened 2 weeks ago

ExplodingLemur commented 2 weeks ago

When I build from the master branch (commit 3f2a5d7) it immediately throws a buffer overflow error and dumps core. This is an x86_64 machine running Ubuntu 24.04. I've included output from make, gdb, and strace below. Let me know if any additional information would help.

make
