I noticed same sporadic messages on Ununtu 8.04.02. Target olpch2294,
GDB port was /dev/ttyUSB0. But when I tried same build and same
configtool on Ubuntu 7.10 I never got the errors. I think that my 8.04
disto has mixed C++ environment. I need (and it is istalled) both
libstdc++ (5 and 6) packages. And my old Ubuntu 7.10 uses libstdc++.so.5
only.
In my environment on Ubuntu 8.04.02 I've got the dependences
~$ ldd /opt/ecos/ecos-3.0b1/tools/bin/configtool | grep stdc++
libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0xb795e000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0xb73c4000)
~$ ldd /opt/ecos/ecos-3.0b1/tools/bin/ecosconfig | grep stdc++
libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0xb7e5a000)
I thought that old release has not the issue that it uses more even
environment. But this is just a guesswork.
CLI GDB session via serial connection work just fine on both distos.
