@	I recently compiled up gcc 2.2.2 for my machine, with the
    intent of doing some C++ programming. While compiling, I found one
    of the files in my distribution to be corrupted. There may have
    been further corruptions, but if there were, they resulted in
    valid 'C' code since a "make bootstrap" completed fine. This may
    or may not have anything to do with my results.

	I then retrieved libg++-2.0, in order to have some basic C++
    classes. While attempting to compile it, gcc (actually cc1plus)
    bombed out with an abort at line 207 of file cp-tree.c. (Like so:

(gdb) run
Starting program: /usr/local/lib/gcc-lib/sun4/2.2.2/cc1plus /usr/tmp/cca28407.i -quiet -dumpbase BitSet.cc -version -o /usr/tmp/cca28407.s
GNU C++ version 2.2.2 (sparc) compiled by GNU C version 2.2.2.

Program received signal 6, Abort
0xf775c120 in kill ()
(gdb) where
#0  0xf775c120 in kill ()
#1  0xf777447c in abort ()

#8  0x7e584 in main (argc=8, argv=0xf7fff8e4, envp=0xf7fff908) at toplev.c:3055
(gdb) 


	After some quick #if 0's, I determined that the line that was
    making it croak was line 768 of BitSettoa.cc, which contained:

      *fmt++ = (a & 1)? t : f;

	Changing the line (and two more just like it in the same
    routine) to either of:

      if (a & 1) *fmt++ = t;
      else *fmt++ = f;

	or

      *fmt = (a & 1)? t : f;
      fmt++;

	would compile fine.


	Does this happen with the "official" 2.2.2 (i.e. do I have a
    improperly built version)? Any chance of getting on a mailing list
    for patches?

	If it matters, I got all my sources from a uunet tape,
    purchased a couple months ago.
