Subject: [PATCH] gnulib/regcomp: Fix uninitialized token structure
|
|
|
468bd4 |
|
|
|
468bd4 |
The code is assuming that the value of br_token.constraint was
|
|
|
468bd4 |
initialized to zero when it wasn't.
|
|
|
468bd4 |
|
|
|
468bd4 |
While some compilers will ensure that, not all do, so it is better to
|
|
|
468bd4 |
fix this explicitly than leave it to chance.
