Hello Again, finally I could reproduce the issue with the current sagemath material
(and the unpatched gap and libgap-sage packages as funishes in unstable).

First I did:
$ DEB_BUILD_PROFILES=pkg.sagemath.ccache DEB_BUILD_OPTIONS="parallel=4 nodoc nocheck" debian/rules build
then
$ export SAGE_LOCAL=$(pwd)/debian/build/usr
$ export PYTHONPATH=$(pwd)/debian/build/usr/lib/python2.7/dist-packages
$ export SAGE_SPKG_INST=$(pwd)/sage/local/var/lib/sage/installed
$ export SAGE_ROOT=$(pwd)/sage
Now
$ ( cd sage; ./sage -t --long src/sage/interfaces/gap.py )
gives

To see what happens on the GAP side, you can begin by uncommenting the seconf bottom line of
debian/build/usr/share/sage/ext/gap/sage.g
namely:
# LogTo("/tmp/gapsage.log");
to
LogTo("/tmp/gapsage.log");
The obtained /tmp/gapsage.log is cacophonous and contains arbitrary bytes .
If you strace the test as follows
$ mkdir /tmp/DEBUG
$ ( cd sage; strace -o /tmp/DEBUG/sage-inter-gap -ff ./sage -t --long src/sage/interfaces/gap.py )
you can more easily catch the `Broken pipe' among one of the nearly 200 strace outputs.
Meanwhile you can split the /tm/gapsage.log trace/log file by replacing the uncommented `LogTo("/tmp/gapsage.log");'
by the following GAP code:
===8><---------------------------------------------------------------------------------------------------------------------------------------------
SAGELOGIDXNAME:="/tmp/gapsage.idx";;
if IsReadableFile(SAGELOGIDXNAME) then
SAGELOGIDXSTREAM:=InputTextFile(SAGELOGIDXNAME);
SAGELOBINDEX:=ReadLine(SAGELOGIDXSTREAM);
CloseStream(SAGELOGIDXSTREAM);
SAGELOBINDEX:=Int(SAGELOBINDEX);
if SAGELOBINDEX = fail then SAGELOBINDEX:=0; fi;
else
SAGELOBINDEX:=0;
fi;;
STRSAGELOBINDEX:=ReplacedString(String(SAGELOBINDEX,4)," ","0");;
SAGELOBINDEX:=SAGELOBINDEX+1;;
PrintTo(SAGELOGIDXNAME,SAGELOBINDEX);;
SAGELOGNAME:=JoinStringsWithSeparator(["/tmp/","gapsage-",STRSAGELOBINDEX,".log"],"");;
####SAGELOGNAME:=JoinStringsWithSeparator(["/tmp/","gapsage-",STRSAGELOBINDEX,"-",String(IO_getpid()),".log"],"");; #### with GAP package io
#
LogTo(SAGELOGNAME);;
- --------------------------------------------------><8===============================================================================================
Note that this very sage test does not involve libgap[-sage].
Please let me know if any precision is needed.
Thanks,
Jerome
