Package: libc0.3
Version: 2.19-22

Hi,
hdf5 recently started to FTBFS on hurd-i386 [1] with no source code
change since the last successful build.
[1] <https://buildd.debian.org/status/fetch.php?pkg=hdf5&arch=hurd-i386&ver=1.8.15-patch1%2Bdocs-4&stamp=1443635447>
The error message says:
LD_LIBRARY_PATH="$LD_LIBRARY_PATH`echo -Wl,-z,relro | \
sed -e 's/-L/:/g' -e 's/ //g'`" \
./H5detect > H5Tinit.c || \
(test $HDF5_Make_Ignore && echo "*** Error ignored") || \
(rm -f H5Tinit.c ; exit 1)
/bin/bash: line 4: 15290 Bus error LD_LIBRARY_PATH="$LD_LIBRARY_PATH`echo -Wl,-z,relro | sed -e 's/-L/:/g' -e 's/ //g'`" ./H5detect > H5Tinit.c
make[3]: *** [H5Tinit.c] Error 1
The Bus error comes from the H5detect execution. Normally the bus error
signal is intercepted by an ad'hoc handler set by H5detect, but that
doesn't work anymore. See H5detect.c after line 63 [2].
[2] <https://sources.debian.net/src/hdf5/1.8.15-patch1%2Bdocs-4/src/H5detect.c/>
I think the cause of this bus error is the upgrade of glibc from
2.19-19 to 2.19-22 because building with libc0.3 from glibc 2.19-19 is
successful.
Using bisection on a porterbox I've found out that the guilty commit is
r6489 [3].

Unfortunately I'm not able to go further understanding the problem.
Could you please revert r6489 or help me fixing H5detect.c in case you
think it's broken?
Many thanks in advance,
_g.
