Hmm, I don't see that symptom, but I do see some strange stuff building
PG CVS tip on a fully-up-to-date (10.4.2) OS X machine. First off,
a lot of duplicate-symbol build warnings, eg while linking pg_dump:
usr/bin/ld: warning multiple definitions of symbol _pg_toupper
../../../src/port/libpgport.a(pgstrcasecmp.o) definition of _pg_toupper in
section (__TEXT,__text)
../../../src/interfaces/libpq/libpq.dylib(pgstrcasecmp.o) definition of
_pg_toupper
/usr/bin/ld: warning multiple definitions of symbol _pg_strncasecmp
../../../src/port/libpgport.a(pgstrcasecmp.o) definition of _pg_strncasecmp in
section (__TEXT,__text)
../../../src/interfaces/libpq/libpq.dylib(pgstrcasecmp.o) definition of

This noise wasn't there ever before; I do not know if it's just that
Apple's tools got pickier recently, or if we've broken something.
Second, at exit from an interactive psql session,
regression=# \q
could not save history to file "/Users/tgl/.psql_history": Invalid argument
$
The file is written, but it seems not to contain the expected contents.
This might be the fault of my not-so-up-to-date readline library.
Not sure if your symptom could also be blamed on readline --- have you
tried getting a stack trace from the crash?
