--- Comment #19 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Andrew Pinski <pins...@gcc.gnu.org>: https://gcc.gnu.org/g:d508d24282c6a8172be2abcb2223232f452b667f commit r16-48-gd508d24282c6a8172be2abcb2223232f452b667f Author: Andrew Pinski <quic_apin...@quicinc.com> Date: Thu Jan 9 12:53:27 2025 -0800 Add assert to array_slice::begin/end So while debugging PR 118320, I found it was useful to have an assert inside array_slice::begin/end that the array slice isvalid rather than getting an segfault. This adds an assert that is only enabled for checking. OK? Bootstrapped and tested on x86_64-linux-gnu. gcc/ChangeLog: * vec.h (array_slice::begin): Assert that the slice is valid. (array_slice::end): Likewise. Signed-off-by: Andrew Pinski <quic_apin...@quicinc.com>
