Hello,
Clicking the middle mouse button in the Lazarus editor window crashes
the IDE with a 'Segmentation fault' if it's compiled for AMD64. The
IDE just exits, and prints "Segmentation fault" on the terminal.
The exact same sources, compiled for i386 work fine, and clicking
the middle mouse button pastes the X selection in the editor.
(as I expected it to do).
Tried on Linux-AMD64, SuSE 10.1, today's SVN version of lazarus and FPC.
backtrace ?
AFAIK, none of the laz devels work on a 64 bit machine, so it is a bit
hard to test/check
Reproduced using remote access over vnc. To me it looks like major heap
corruption.
Backtraces obtained using gdb from the command line.
