The test fails in the debug code of changed_page_bitmap.cc, at the last test step, where it attempts to perform a bitmap backup (LSNs 9000..infinity)) with bitmap data missing for the start of interval.
With PS 5.6.11 the bitmap files are as follows:
/home/laurynas/percona/src/bug1204075/test/var/w1/var1/data/ib_modified_log_4_1633805.xdb
/home/laurynas/percona/src/bug1204075/test/var/w1/var1/data/ib_modified_log_5_1634123.xdb
With PS 5.5 the bitmap files are as follows:
/home/laurynas/percona/src/bug1204075/test/var/w1/var1/data/ib_modified_log_4_1602083.xdb
/home/laurynas/percona/src/bug1204075/test/var/w1/var1/data/ib_modified_log_5_1602404.xdb
I.e. identical for the purposes of the test. Given that xtradb51 and xtradb55 debug configurations are disabled in Jenkins and at least the xtradb55 one does not even build, I believe this bug has been from day one and surfaced on the first actually enabled debug xtradb configuration.
