Package: unifdef
Version: 1.0+20030701-1
Severity: important
Running "unifdef -UBARF" over the file:
char foo[] = "rm -rf /*";
causes a warning that the file ends within a comment. That's not so
bad. However, since the text following up to the next "*/" will be
considered to be in a comment, it won't go through proper unifdef
processing:
$ cat unifdef-test.c
#ifdef FOO
int a;
#endif
char foo[] = "rm -rf /*";
#ifdef FOO
int b;
#endif
/* baz */
$ unifdef -UFOO < unifdef-test.c
char foo[] = "rm -rf /*";
#ifdef FOO
int b;
#endif
/* baz */
$
Workarounds:
Immediately follow any such string literals with /* */ comments.
Use "\" before the "*", though that generates a warning from gcc about
an unknown escape sequence.
Construct the string literal from two, e.g.:
char foo[] = "rm -rf /" "*";
