LAST_UPDATED: Obtained from SVN: tags/gcc_4_1_2_release revision 121944

Native configuration is sparc64-unknown-linux-gnu


The g++ testsuite, with -m64, fails (ICE) with these two test cases:

Running target unix/-m64
FAIL: tmpdir-g++.dg-struct-layout-1/t026 cp_compat_x_tst.o compile,
(internal compiler error)
FAIL: tmpdir-g++.dg-struct-layout-1/t026 cp_compat_y_tst.o compile,
(internal compiler error)

Looking at the log file, we see 

> FAIL: tmpdir-g++.dg-struct-layout-1/t026 cp_compat_x_tst.o compile,
> (internal compiler error)
