Heads up, re a nasty GCC bug, apparently ignored for a long time?

According to the
gcc bugzilla entry the problem is present in gcc versions 4.4.0-4.4.5. The version of avr-gcc packaged with the ZBasic compiler is 4.3.3 (WinAVR-20100110). Nonetheless, it will be well to keep this in mind for future releases.

do you think GCC will be adequately sustained now that they cut off the paid support for Studio 4/WinAVR?
Studio 5/6 of course use GCC but I wonder who is and will for the long run keep GCC bug free for AVR?

It is fairly likely, I think. Atmel is required to make available any patches that they make to gcc. Further, there are several people outside of Atmel that have expertise in different areas of avr-gcc.

The long time WinAVR sustainer (with Atmel funding I think) was Eric Weddington).
A few months ago, I read that Atmel stopped funding him.
I suppose you are close to all of this, having a vested interest!
