@ 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)
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.
