There was 1 failure:

/build/phpmyadmin-4.9.2+dfsg1/test/classes/EncodingTest.php:98

I tried to fix it upstream in 4.9.2 but I seems not to be enough.

testDetectType fail in i386 (NOT ANYMORE with 4.9.2)

There were 2 failures:

1) PhpMyAdmin\Tests\ImportTest::testDetectType with data set #9 (4, 4, '2147483648')
Failed asserting that 1 matches expected 4.

2) PhpMyAdmin\Tests\ImportTest::testDetectType with data set #10 (4, 2, '2147483648')
Failed asserting that 1 matches expected 4.

https://tests.reproducible-builds.org/debian/rb-pkg/unstable/i386/phpmyadmin.html It is because it is 32bit system and fixed it upstream in 4.9.2.
