I am using texinfo-6.8-4.fc37. Hardened malloc[1] is a security focused malloc implementation. According to them, crashes are usually bugs in the application because they are more strict than the glibc malloc. When running info -a arg, this occurs:
fatal allocator error: canary corrupted
Here is the backtrace:
