git head crash/regression failures

I am seeing psql crash and massive regression test failures in git head.
The psql crash happens if .psqlrc contains:

\set COMP_KEYWORD_CASE upper

and the crash backtrace is:

Program received signal SIGSEGV, Segmentation fault.

The regression test seem to be crashing from \d. For example, in
src/test/regress/results/tablespace.out, once this line appears:

\d testschema.test_index1

the file ends, while the expected file has many more lines.
