[fpc-pascal]fpc 1.9.0 beta - error 200306065

[paradice]

I get the above error code when compiling a specific unit with the new 1.9.0
beta under Win32.

It doesn't occur under either 1.0.10 or 1.0.6, which are the other two
versions I keep around to test things. It only occurs when *compiling* the
unit. When *building* the unit, it compiles perfectly, but if I immediately
try to compile after this, I get the same error again.

I would post the unit on my website & make a link here, except it's tied in
to quite a few others...

any ideas?
