[fpc-pascal] Error compiling FPC trunk x64 Windows

[Reinier Olislagers]

I've been having errors compiling FPC trunk x64 on Windows with fpcup
for a while now.

Current output (rev 22336)
C:/development/fpcbootstrap64/ppcx64.exe -Ur -Xs -O2 -n -Fi../inc
-Fi../x86_64 -FE. -FUC:/development/fpctrunk/rtl/units/x86_64-win64 -gw
-gl   -dx86_64 -dRELEASE -Us -Sg system.pp -Fi../win
generic.inc(2505,13) Fatal: Internal error 8
Fatal: Compilation aborted

Removing entire source directory and doing a new checkout didn't help.

x86 used to have problems too, but compiles again.

Does anybody else see this?

Thanks,
Reinier
