If you want to spend some time on it and know a little assembler you can 
  get the assembler source by using the -al compiler options.

So I would do the following:
* compile the LCL: make lcl
* remove the lcl/units/sparc-linux/graphics.ppu
* recompile the graphics unit: make lcl OPT="-al"
* inspect the graphics.s file and look for line 230 of pen.inc to see 
what causes the sigbus.
