Uh... if I compile with "-g -O0" only 15 tests fail, and I get no

Can you try adding a "-b" to all the instances of "diff" in
tests/command/npar-binomial.sh, tests/command/npar-chisquare.sh and
tests/command/very-long-strings.sh
I *think* this will fix these three failures.
If this helps, I have put up a log with "-g -O2" at:
http://www.csse.uwa.edu.au/~john/make.check.2007-02-17.gO2.log.bz2
Many (all?) of the seg faults here have the form:
Backtrace:
=>1 0x601b79dc memcpy+0x1c() in libc.so.6 (0x0099fc28)
2 0x00458769 dfm_put_record+0xc9(w=0x126e10, rec=0x12e500, len=0x4)
[/opt/user/cross-tools/bin/../lib/gcc/i386-mingw32msvc/3.4.1/../../../../i386-mingw32msvc/include/stdio.h:262]
in pspp (0x0099fc58)
So it looks as if there may be a problem with dfm_put_record.
Examining that function, I'm suspicious, because:
switch (fh_get_mode (w->fh))
{
case FH_MODE_TEXT:
fwrite (rec, len, 1, w->file);
putc ('\n', w->file);
break;
case FH_MODE_BINARY:
{
size_t record_width = fh_get_record_width (w->fh);
size_t write_bytes = MIN (len, record_width);
size_t pad_bytes = record_width - write_bytes;
fwrite (rec, write_bytes, 1, w->file);
... the tests for record_width are not performed in the first case.
And this case I suspect never arises except under windows. I suggest
that we start by putting some assertions in the first case of this
switch and see what happens.
