If we're setting ssh->s to NULL, we ought to free the thing it previously pointed to (having extracted the error message first). At the very least this is a memory leak. But in fact it's worse, because not freeing it also means not cancelling its toplevel callbacks. And if you don't do that, then a failure to set up an SSH connection proxied over another SSH connection will generate two error dialog boxes in succession, the second one from the callback that should have been cancelled here. On Windows that callback never gets called, because we exit the whole process before getting into the main message loop which might run the callback. But on Unix, we do go to the main message loop (we don't have a separate one for the error box), which causes an assertion failure in register_dialog() when the second box finds the DIALOG_SLOT_CONNECTION_FATAL slot already occupied. |

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.
