Nick,
   I can confirm that passing "-Wl,-no_compact_unwind" to the failing
testcase for g++.dg/torture/stackalign/eh-vararg-2.C eliminates the
run-time error. I'd run the entire testsuite with that approach but
I don't know how to suppress the comma in...

make -k  check RUNTESTFLAGS="--target_board=unix'{-Wl,-no_compact_unwind}'"

so that it runs as a single test passing "-Wl,-no_compact_unwind".
