As a last resort, maybe. But you still didn't investigate the bug that
you originally reported: remember "do ble"?
/usr/local/src/FlightGear/src/Main/fg_init.cxx:628: undefined reference to
`FGNullFDM::FGNullFDM(do ble)'
Have you ever looked into fg_init.cxx, line 628? (Things have changed
meanwhile, so if you are using CVS HEAD, this won't be in line 628 any more.)
Is there really a "do ble" instead of "double"?

Ahh, but you =have= modified the code? Nobody else seems to be able to
reproduce your problems. Does "cvs up" report any modifications? ("M" in
the first column.)

Did you ever update all or only some files to a particular version or date,
as in "cvs up -D '2 weeks ago'" or "cvs up -r1.23 file.cxx"? This leaves
so-called sticky tags or dates in CVS/Entries. Updating will then always
only update to the same "sticky" versions. In this case update all of your
fgfs sources like this:
$ cvs up -dPA
Mind the "A"! It brings you back to CVS HEAD, the very last version.

Yes. But it's always the same bug(s)? Otherwise checking your RAM is the way to
go: memtest86 :-)

That sounds very much like problems with "sticky tags/dates"! See above.
Unless you have already done a "cvs up -A" you can try this in your source
directory:
$ cvs status|grep Sticky|grep -v "(none)"
If it outputs =any= line, then "cvs up -A" will solve your problems.

We =do= think about it and we =do= care. But it's quite hard to find
irreproducible bugs. (A telnet/ssh account on your machine would help. ;-)
