Recent alpha regression

[Tom Tromey]

I'm building the latest cvs gcc on this box:

    castro. uname -a
    Linux castro.cygnus.com 2.2.13-0.9smp #1 SMP Thu Dec 9 16:27:46 EST 1999 alpha unknown


I'm building with java, of course.

This gcc now fails to compile libgcj.  I could compile libgcj a few
days ago.

Here's the failure:

/horton/tromey/java/build/gcc/gcj -B/horton/tromey/java/build/alphaev6-unknown-linux-gnu/libjava/ -B/horton/tromey/java/build/gcc/ --encoding=UTF-8 -fassume-compiled -fclasspath=/horton/tromey/java/build/alphaev6-unknown-linux-gnu/libjava -L/horton/tromey/java/build/alphaev6-unknown-linux-gnu/libjava -g -mieee -MD -MT java/util/SimpleTimeZone.lo -MF java/util/SimpleTimeZone.d -c ../../../gcc/libjava/java/util/SimpleTimeZone.java -fPIC -o java/util/.libs/SimpleTimeZone.o

../../../gcc/libjava/java/util/SimpleTimeZone.java:570: Internal error: Segmentation fault.


Here's a stack trace of the failure:

(at this point gdb died, so I don't know about higher up the stack)
