This question relates to this thread, however that thread has no answers so this it not technically a duplicate.
I\'ve got ADB 1.0.26 running on my Windows 7 x64 and
this patched adb version worked fine for me (HTC Desire HD): http://code.google.com/p/android/issues/detail?id=12141
Do you have the Revolution 4G ROMs installed? If so, then I had to install the no-sense patch to remove all the HTC stuff. Once I did that, ADB stopped crashing in Eclipse.
Edit - Actually it seems like it still crashes sometimes, but not as often? Still not a solution.
For this go to DDMS, Look for Devices-->View Menu-->Reset adb.
