| Subject: [PATCH] gnulib/regcomp: Fix uninitialized token structure |
| |
| The code is assuming that the value of br_token.constraint was |
| initialized to zero when it wasn't. |
| |
| While some compilers will ensure that, not all do, so it is better to |
| fix this explicitly than leave it to chance. |
| |
| Fixes: CID 73749 |
