From 0d29e84f3a0a7b56f5703b771e1316461b66c91a Mon Sep 17 00:00:00 2001 From: Nic Boet Date: Thu, 1 Oct 2026 23:09:17 -0500 Subject: [PATCH] Fix segfault with -f when TERM is unset The -f handling passed getenv("TERM") straight to strcmp(), which crashes when TERM is not set. Treat an unset TERM like any other non-"linux" value and set it to "linux". Fixes #174. --- cmatrix.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/cmatrix.c b/cmatrix.c index 7d8ca39..4902495 100644 --- a/cmatrix.c +++ b/cmatrix.c @@ -436,7 +436,7 @@ int main(int argc, char *argv[]) { _putenv_s("TERM", ""); #endif - if (force && strcmp("linux", getenv("TERM"))) { + if (force && (getenv("TERM") == NULL || strcmp("linux", getenv("TERM")))) { #ifdef _WIN32 SetEnvironmentVariableW(L"TERM", L"linux"); #else
