Severity: normal

Dear maintainer,
The galera-3 package was failing to build from source on armhf in Ubuntu,
because the Ubuntu armhf autobuilders expose unaligned accesses as SIGBUS
and galera-3's code makes an unaligned access that gets caught by the test
suite.
Please find attached a fix for this portability bug.
Thanks,

+Description: avoid unaligned dereferencing of a byte array
+ The checksum verification code casts from memory at an arbitrary offset of
+ a byte array to a uint64_t*, then dereferences it. This is non-portable
+ because it results in unaligned access.
+ .
+ Work around this by just reading byte-for-byte and bitshifting into the
+ result.
