Bug#847288: libdbd-firebird-perl: FTBFS randomly (failing tests)

[Santiago Vila]

Package: src:libdbd-firebird-perl
Version: 1.24-1
Severity: serious

Dear maintainer:

I tried to build this package in stretch with "dpkg-buildpackage -B"
but it failed:

--------------------------------------------------------------------------------

Result: FAIL
Failed 4/88 test programs. 0/1111 subtests failed.
Makefile:1062: recipe for target 'test_dynamic' failed
make[1]: *** [test_dynamic] Error 255
make[1]: Leaving directory '/<<PKGBUILDDIR>>'
dh_auto_test: make -j1 test TEST_VERBOSE=1 returned exit code 2
debian/rules:14: recipe for target 'build-arch' failed
make: *** [build-arch] Error 2
dpkg-buildpackage: error: debian/rules build-arch gave error exit status 2
--------------------------------------------------------------------------------

The error happens randomly, but always in some autobuilders and never
in some others, which is strange because all my autobuilders are
configured the same way.

Last time I got a build failure like that (which happened or not
depending on the autobuilder) it was a bug related to filesystem
ordering:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=841096#32

but of course this one may be completely different.

I attach several build logs.

Thanks.
