Yes. It's possible to get `argc` to equal zero, though by invoking the program using `execve(prog, {NULL}, {NULL})` on Linux. This has, rather famously, caused at least one out-of-bounds error in a security-critical program (CVE-2021-4034 "Pwnkit", LPE by invoking Polkit's pkexec with a zero-length argv). |
