Re: [Simulavr-devel] Crash after entering 'target remote localhost:1212' in avr-gdb

[Klaus]

Hi Albrecht,

please check my latest commit.

Please do the following commands:

make distclean
git pull
./bootstrap
./configure
make
make install

I tested as described in the bug tracker.

If there are still issues, feel free to reopen the bug or if you find 
something new, open another one.

I hope the fix ok.

Please give a short notice after you have tested the changes.

Thanks
 Klaus
