Possible bug in strace functionality (or CVS)

["Neil Erskine" <neil dot erskine at jjmackay dot ca>]

I find that the attached script fails on Windows 98 and Windows 200 when
running Cygwin 1.3.2 with CVS 1.11.  A core dump occurs in the "strace cvs
commit" line.  Removing the "strace" term allows the script to run to
completion.  I hope that someone with greater familiarity with how strace
works will be able to take a look at it.

The strace shows that an open call succeeds, and an uncaught exception
occurs after the open returns.
