| Crash with empty Labels on Linux [message #198469] |

instantiating Labels (from draw2D) with no initial text the application
crashes with following error (only on linux, on windows the application
works fine):
------------------------------------------------------ The
program 'SWT' received an X Window System error. This probably reflects a
bug in the program. The error was 'BadAlloc (insufficient resources for
operation)'.
(Details: serial 4345 error_code 11 request_code 53 minor_code 0) (Note
to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it. To debug
your program, run it with the --sync command line option to change this
behavior. You can then get a meaningful backtrace from your debugger if
you break on the gdk_x_error() function.)
----------------------------------------------------- Trying to find a
workaround I set a MarginBorder(1) on the Label the problem seems to be
resolved.
regards

Hi,
I will provide a snippet as soon as possible. Unfortunately I can
reproduce the problem only on our application, but not in a simple
standalone.

Good call. If you enable tracing for org.eclipse.ui, one of
the options is "debug/swtdebug". This _should_ enable both Device.DEBUG
and data.debug, but it may only do the latter which would be less useful
in this case.
Try swtdebug, and if you don't get a stack trace, file a bug against
Platform > UI asking for more tracing options :)
