Simon Tatham c2d7ea8e67 Fix use of aligned_alloc() to be ASan-clean.
aligned_alloc() is used by testsc for all its memory allocation, to
avoid false-positive timing variations that depend on memory alignment
rather than actual secret data. But I'd forgotten that aligned_alloc
requires the allocation size to be a multiple of the requested
alignment.

This showed up when I ran testsc in dry-run mode, and my normal build
happened to be using ASan, which complains at the invalid allocation
size. But it was theoretically a problem in all builds of
testsc. (Though, as far as I'm aware, not practically; and it _only_
affected testsc.)

PuTTY source code README
========================

This is the README for the source code of PuTTY, a free Windows and
Unix Telnet and SSH client.

PuTTY is built using CMake <https://cmake.org/>. To compile in the
simplest way (on any of Linux, Windows or Mac), the general method is
to run these commands in the source directory:

  cmake .
  cmake --build .

These commands will expect to find a usable compile toolchain on your
path. So if you're building on Windows with MSVC, you'll need to make
sure that the MSVC compiler (cl.exe) is on your path, by running one
of the 'vcvars32.bat' setup scripts provided with the tools. Then the
cmake commands above should work.

To install in the simplest way on Linux or Mac:

  cmake --build . --target install

On Unix, pterm would like to be setuid or setgid, as appropriate, to
permit it to write records of user logins to /var/run/utmp and
/var/log/wtmp. (Of course it will not use this privilege for
anything else, and in particular it will drop all privileges before
starting up complex subsystems like GTK.) The cmake install step
doesn't attempt to add these privileges, so if you want user login
recording to work, you should manually ch{own,grp} and chmod the
pterm binary yourself after installation. If you don't do this,
pterm will still work, but not update the user login databases.

Documentation (in various formats including Windows Help and Unix
`man' pages) is built from the Halibut (`.but') files in the `doc'
subdirectory. If you aren't using one of our source snapshots,
you'll need to do this yourself. Halibut can be found at
<https://www.chiark.greenend.org.uk/~sgtatham/halibut/>.

If you want to send bug reports or feature requests, please read the
Feedback section of the web site before doing so. Sending one-line
reports saying `it doesn't work' will waste your time as much as
ours.
