Trunk (as of yesterday evening), 2.6.4, export OPT='-O- -gl', make all,
run with ./lazarus --sync --g-fatal-warnings.
The machines here are generally Debian with KDE as a desktop, but the
"Wheezy" systems are closely modelled on the older "Squeeze" ones. It
appears that if I run on the machine's own display it works, but if I
attempt to run Lazarus over SSH (a combination that works on all other
systems around here and with numerous programs on the test systems) it
$ ./lazarus --sync --g-fatal-warnings
Xlib: extension "RANDR" missing on display "localhost:10.0".
The program 'lazarus' received an X Window System error.
This probably reflects a bug in the program.
The error was 'RenderBadPicture (invalid Picture parameter)'.

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()
Is OK over a remote X session (i.e. running in Xnest). An initial
successful run to set up ~/.lazarus doesn't improve the situation over
SSH but gets it to the point where lazbuild works.
However I also find that a program built using Lazarus (IDE or lazbuild)
fails on that system (i.e. Wheezy) in the same way as the IDE.
