I only observed this in the GTK1 build, but I don't know for sure it can't happen in other situations, so there's no reason not to be careful. What seems to happen is that when the user clicks Cancel on the Change Settings dialog box, we call gtk_widget_destroy on the window, which emits the "destroy" signal on the window, our handler for which frees the whole dlgparam. But _then_ GTK goes through and cleans up all the sub-widgets of the dialog box, and some of those generate extra events. In particular, destroying a list box is done by first deleting all the list entries - and if one of those is selected, the list box's selection changes, triggering an event which calls our callback that tries to look up the control in the dlgparam we just freed. My simple workaround is to defer actually freeing the dlgparam, via a toplevel callback. Then it's still lying around empty while all those random events are firing. |

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/>. The PuTTY home web site is https://www.chiark.greenend.org.uk/~sgtatham/putty/ 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. See the file LICENCE for the licence conditions.
