-Subject: [PATCH 19/23] [fts2][backport] Fix misaligned address in icu
- tokenizer.
-
-Fix the problem that an int* pointer is assigned with a value calculated
-from a UChar* pointer and an offset. If the offset is odd, the int* pointer
-will not be 4-byte aligned which causes SIGBUS on some CPUs.
-
-Please see #9 and #10 in crbug.com/151673 for details.
