Thanks, that worked.
Obviously you'd lose debuggability but that might or might not be a
problem for your particular use case.
Well, I am just build testing.
I am wondering if the latest GCC 4.5 changes are causing this, but as
always this is just an uneducated guess.
Could be. Or it's possible that the bug has been latent for a long time
and has just been tickled by a recent change to CFLAGS. I think the
inclusion of -g in the default opts is a relatively recent innovation.
I think it worked before last Friday, i. e., before the GCC 4.5 updates.
Yes and the fix was to address exact same problem but reported in
another recipe. So it fixed things but partially. Let me try to poke
around a bit
You could bisect the recent changes if you want but, unless you want to
debug this for yourself, the best way to proceed is probably to follow
the directions in the error message and submit a bug report to upstream
GCC.
I will see, if or when I will get to that and report back.
Thanks,
Paul
