I hear that segmenation faults happen when the computer tries to follow
a null pointer. the getenv() function returns NULL when that function
fails. So why not try something likes this?
printf("Content-type: text/html\n\n");
if (getenv("QUERY_STRING") != NULL)
{
line_buffer = (char *) malloc(strlen(QUERY_STRING) + 1);
strcpy(line_buffer, getenv("QUERY_STRING");
}
