Subject: Inappropriate code style for Intel MPX in elf/dl-close.c
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5dad50d8242a59291294a71c0d48aec966880c32;p=thirdparty%2Fglibc.git

Inappropriate code style for Intel MPX in elf/dl-close.c
A cast implies memory access with bounds violation.
Let allow that.
