awk: fix read beyond end of buffer
|
||||
Commit 7d06d6e18 (awk: fix printf %%) can cause awk printf to read
|
||||
beyond the end of a strduped buffer:
|
||||
|
||||
2349 while (*f && *f != '%')
|
||||
2350 f++;
|
||||
2351 c = *++f;
|
||||
|
||||
If the loop terminates because a NUL character is detected the
|
||||
character after the NUL is read. This can result in failures
|
||||
depending on the value of that character.
