H&S testcase fails

Testing latest version (d1fbf10f) on Irene-Rome, the provided H&S testcase fails with an error triggered by XIOS (xios_client_*.err files):

In file "nc4_data_output.cpp", function "void xios::CNc4DataOutput::writeAxis_(xios::CAxis *)",  line 1414 -> On writing the axis : nq
In the context : icosagcm_server
Error when calling function ncPutVaraType(ncid, varId, start, count, data)
NetCDF: HDF error
Unable to write data given the location id: 262144 and the variable whose id: 4 and name: nq

Problem clearly related to number of tracers as setting "nqtot=1" in run.def avoid running into it.
