The target triplet seems to be any PowerPC (:-) target:
powerpc-eabisim, powerpc-unknown-linux-gnu, powerpc-ibm-aix4.3.3.0 .
The failure, as Janis mentioned, is g++.dg/compat/break/bitfield7_y.C
which as an ABI compatibility test expands on the original
g++.dg/abi/bitfield7.C test. bitfield7.C *does not* access the field and
does not ICE. Only Janis's new test, bitfield7_y.C, operates on the
bitfield eliciting the ICE. This may be a failure which only visibly ICEs
on big-endian targets due to the logic in extract_bit_field.
