Source: mpd Version: 0.19.14-2 Severity: important Justification: fails to build form source (but built in the past) Tags: patch User: debian-alpha@lists.debian.org Usertags: alpha mpd FTBFS on Alpha with a failure in the test suite [1]: FAIL: test/test_byte_reverse ============================ .F... !!!FAILURES!!! Test Results: Run: 4 Failures: 1 Errors: 0 1) test: ByteReverseTest::TestByteReverse2 (F) line: 58 test/test_byte_reverse.cxx assertion failed - Expression: strcmp(result, (const char *)dest) == 0 This occurs because the test suite (in test/test_byte_reversal.cxx) allocates static char arrays and passes the char arrays to functions whose respective arguments were declared to be uint16_t *, etc., in the main code. This is in the realm of undefined behaviour on architectures with strict memory alignment requirements. Although the test only fails on Alpha (because Alpha has a particular CPU load instruction that gcc likes to use to add bugs ..., ahem, optimise the code on the assumption of alignment) it is potentially a latent bug for other architectures with strict alignment requirements. Since the code is compiled with the c++11 standard I attach a patch that modifies the test suite to align the non-compliant strings with the alignas() attribute. The test suite now passes on Alpha with that patch. Cheers Michael [1] https://buildd.debian.org/status/fetch.php?pkg=mpd&arch=alpha&ver=0.19.14-2&stamp=1461542099
