There's Ziegler's paper, which you know about, at
http://archive.adaic.com/intro/ada-vs-c/cada_art.html#xtocid153455
(for those who don't know about it) and there was a posting here on c.l.a by
Marin Condic about jet-engine control S/W at Pratt & Whitney that reported
similar results; about 4 times the errors and about 10 times the effort per
error was the average I took away from those.
Some would also cite McCormick's real-time course results for this, but while it
clearly shows reduction in development effort for Ada compared to C, since no
one ever finished the project in C, I can't see that it provides any information
on error rates. Information about it is at
http://static1.1.sqspcdn.com/static/f/702523/9458053/1290008042427/200008-McCormick.pdf?token=C60YTOwv6V6y%2BJDCChhjKp2Vp4U%3D
for those not familiar with it.
