Hello, In the last few weeks a series of mallocs diff have been committed. The last one today. That one allows malloc to detect more cases of write-after-free. While that is a good thing, it might uncover latent bugs in appliations.
So if you are running current or snapshots, please keep an eye out for issues reported by malloc. If we get too many reports of issues I might change things so the extra write-after-free detetecion is ony enabled when malloc option S is active. -Otto
