I tried to run it with --gdk-fatal-warnings. The problem is that another gdk-warning takes place during a form creation (even for empty form). Course, it halts execution on startup. I tried both 1.1 and 1.0.7 fpcs.

Any gdk warning is a bug.
Please report them (Send the gdb backtrace).

That was a shm-bug. --no-xshm fixed the first bug... But did nothing with second (Bad drawable). --g-fatal-warnings in gdb did nothing too (program died without any break in gdb).

I tried to run it with --gdk-fatal-warnings. The problem is that another gdk-warning takes place during a form creation (even for empty form). Course, it halts execution on startup.
I tried both 1.1 and 1.0.7 fpcs.

Seems like another mail service wasn't able to post messages to discussion.
I have written a program
http://www.ussr.to/Russia/vvi/fpclcl/salting.tgz
But when creating and modal showing a new form (in menu item click handler), program can unexpectively die (but can not) with gdk-error about invalid window or pixmap. Seems that it is a bug of lcl/gtk/gdk.

Never saw such a thing.
Can you send the whole output?

I'll do that as soon as I'll use my own PC. Besides, I can't send any message from home as I can't use my work's smtp.
The error was "Function not implemented", #22
Both fpc-1.1 and 1.0.7 reported it.

I tried without problems. Maybe it has something to do with the compiler.

- Please add the memcheck unit as first unit to your lpr source to find any mem corruption.
- Run the program with the parameter '--g-fatal-warnings', so that the gdb warnings will immediately stop the program and you can see the call stack
- check with ldd if your program uses only the gtk libs and no gtk-2.x or glib-2.x libs.
