[Rd] core Matrix package segfaulted on R CMD check --use-gct

[luke-tierney at uiowa.edu]

Given the configure settings this looks like its probably an issue in
regexpr's internals rather than in Matrix per se. I can confirm that
with

Error in regexpr("package:", "package:lattice", fixed = TRUE) :
   unprotected object (0x26b30a8) encountered (was INTSXP)

run in r55347 with --enable-strict-barrier.  I'll see if I can spot anyting.
