On x86_64-unknown-netbsd9.3, running Autoconf's test suite consistently
produces this failure:
Failed tests:
NUM: FILE-NAME:LINE TEST-GROUP-NAME
270: torture.at:913 Substitute and define special characters
This test checks whether it is possible to pass a string through AC_SUBST that
includes a byte with every possible value except 0x00.
The log for the testsuite says
configure: creating ./config.status
config.status: creating Foo
config.status: creating Zardoz
config.status: creating config.h
./torture.at:987: cat Foo
./torture.at:1000: cmp allowed-chars Zardoz

+allowed-chars Zardoz differ: char 256, line 2
./torture.at:1000: exit code was 1, expected 0
Comparing hex dumps of the files "allowed-chars" and "Zardoz" shows that the
problem is that an extra byte (with value 0x81) has been inserted before each
byte with a value in the range 0x81 through 0x8b. The extra bytes are *not*
present in the value of @zardoz@ recorded in config.status, but they *are*
present in the temporary file `subs1.awk` used by config.status (to see this
file run `./config.status -d` and then look in the directory named confXXXXXX,
where XXXXXX is some random sequence of alphanumerics). Thus, this appears to
be a bug in the handling of here documents in this system's /bin/sh. However,
the obvious cut-down version of the code in config.status does _not_ show the
bug:
$ printf 'xxd
<<\\EOF\n\x80\x81\x82\x83\x84\x85\x86\x87\n\x88\x89\x8a\x8b\x8c\x8d\x8e\x8f\nEOF\n'
> test.sh
$ /bin/sh test.sh
00000000: 8081 8283 8485 8687 0a88 898a 8b8c 8d8e ................
00000010: 8f0a ..
We need to pin down exactly what the bug is before we can do anything about
it.
If you encounter a failure in this test on any platform _besides_
*-unknown-netbsd9*, please post a comment here. Please attach a tarball of
the directory tests/testsuite.dir/270 (note: the number may be different if
you are testing a version of Autoconf other than 2.72).
