+Subject: [PATCH] regression_8100: use null terminated strings with file_to_c
+
+GCC 9 is more strict with string manipulation, causing the build to
+fail as the string data converted via file_to_c is not null terminated,
+as described by the following build error:
+
+regression_8100.c:100:29: error: '%*s' directive argument is not a
+nul-terminated string [-Werror=format-overflow=]
+tlen = myasprintf(&trust, "%*s", (int)sizeof(regression_8100_ca_crt),
+                           ^~~
+      regression_8100_ca_crt);
+      ~~~~~~~~~~~~~~~~~~~~~~
+
+Change file_to_c to terminate the string after conversion and update the
+string size to remove the null terminated byte. Also update
+regression_8100 to use the size variable defined via file_to_c instead
+of manually calling sizeof.
