+Subject: [PATCH] iconv: Fix incorrect UCS4 inner loop bounds (BZ#26923)
+
+Previously, in UCS4 conversion routines we limit the number of
+characters we examine to the minimum of the number of characters in the
+input and the number of characters in the output. This is not the
+correct behavior when __GCONV_IGNORE_ERRORS is set, as we do not consume
+an output character when we skip a code unit. Instead, track the input
+and output pointers and terminate the loop when either reaches its
+limit.
+
+This resolves assertion failures when resetting the input buffer in a step of
+iconv, which assumes that the input will be fully consumed given sufficient
+output space.
+
+Upstream-Status: Backport [https://sourceware.org/git/?p=glibc.git;a=commit;h=228edd356f03bf62dcf2b1335f25d43c602ee68d]
