compiler failures on buildfarm member wombat

Hi,

Wombat has dyed of internal compiler errors twice lately:

http://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=wombat&dt=2009-03-08%2004:30:01
gistget.c: In function 'gistnext':
gistget.c:358: internal compiler error: Segmentation fault
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://bugs.gentoo.org/&gt; for instructions.

It has failed in different ways in the past, for example

http://buildfarm.postgresql.org/cgi-bin/show_log.pl?nm=wombat&amp;dt=2008-12-31%2004:30:01
ccache gcc -O2 -Wall -Wmissing-prototypes -Wpointer-arith -Wdeclaration-after-statement -Wendif-labels -fno-strict-aliasing -fwrapv -g -fpic pg_regress.o pg_regress_main.o -L../../../src/port -Wl,--as-needed -Wl,-rpath,'/home/markwkm/local/pgfarmbuild/HEAD/inst/lib' -lpgport -lxslt -lxml2 -lssl -lcrypto -lkrb5 -lz -lreadline -lcrypt -ldl -lm -o pg_regress
collect2: ld terminated with signal 11 [Segmentation fault]
make[2]: *** [pg_regress] Error 1

Could this be due to hardware problems?
