There's this paper in CrossTalk, from 2003 - which comes to very
different conclusions to Les Hatton's paper (see the table about 2/3
into the paper).
http://www.stsc.hill.af.mil/crosstalk/2003/11/0311german.html

"Table 1 shows that the poorest language for safety-critical
applications is C with consistently high anomaly rates. The best
language found is SPARK (Ada), which consistently achieves one anomaly
per 250 software lines of code. The average number of safety-critical
anomalies found is a small percentage of the overall anomalies found
with about 1 percent identified as having safety implications.
Automatically generated code was found to have considerably reduced
syntactic and data flow errors."
