+Subject: fix integer promotion bug in partition size check
+X-Git-Url: https://review.webmproject.org/gitweb?p=libvpx.git;a=commitdiff_plain;h=9fb80f7170ec48e23c3c7b477149eeb37081c699
+
+fix integer promotion bug in partition size check
+
+The check '(user_data_end - partition < partition_size)' must be
+evaluated as a signed comparison, but because partition_size was
+unsigned, the LHS was promoted to unsigned, causing an incorrect
+result on 32-bit. Instead, check the upper and lower bounds of
+the segment separately.

+Upstream-Status: Inappopriate [upstream has it done in other way]
