Subject: fix missing flush of stderr at exit if it was put in buffered mode
X-Git-Tag: v1.1.20~9
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=ddc947eda311331959c73dbc4491afcfe2326346;p=oweals%2Fmusl.git

fix missing flush of stderr at exit if it was put in buffered mode

commit 0b80a7b0404b6e49b0b724e3e3fe0ed5af3b08ef added the ability to
set application-provided stdio FILE buffers, adding the possibility
that stderr might be buffered at exit time, but __stdio_exit did not
have code to flush it.

this regression was not present in any release.
