FPC trunk building lazarus trunk fails with compiler AV ?
An old ghost seems to have resurfaced. I didn't build a development lazarus for a while (I used a stable one for work),
but at least 1-2 weeks I have this problem:

(3104) Compiling printers.pas

Compiler AVs in postscript* units have happened before afaik.
Any pointers?
I've tried to reproduce the AV while building Lazarus on i386-win32 with -O2
and -O3 options, but it works for me.
What compiler options have you used to build Lazarus?
Yuriy.
