The card string is used in a getcwd(card, SZ_PATHNAME) call. The man page of getcwd (3) says:
card
getcwd(card, SZ_PATHNAME)
char *getcwd(char *buf, size_t size); [...] The size argument is the size in bytes of the character array pointed to by the buf argument.
char *getcwd(char *buf, size_t size);
size
buf
SZ_PATHNAME is set to 511; however card had only 256 chars. With hardening enabled, this results in a segmentation fault on Debian.
SZ_PATHNAME
This patch just increases the size of card to the necessary value.
