make PROFILE=-pg segment fault - Mailing list pgsql-bugs

I do "make PROFILE=-pg" on top level, seems everything is ok. When
postmaster starts up, gmon.out is generated. But when I do use psql to
connect to postmaster, a repeatable segment fault happens no matter what
command you do in psql:

sh-2.05a$ psql test
Welcome to psql 8.1RC1, the PostgreSQL interactive terminal.

       \? for help with psql commands
       \g or terminate with semicolon to execute query
       \q to quit

test=# create table m(i int);
LOG:  unexpected EOF on client connection

No strange usage of "PROFILE" in makefiles:
/h/164/zhouqq/pgsql#find . -name "*akefile*" -exec egrep -Hn "PROFILE" {}
\;
./src/Makefile.global.in:404:ifdef PROFILE
./src/Makefile.global.in:405:   CFLAGS += $(PROFILE)
./src/Makefile.global.in:406:   LDFLAGS += $(PROFILE)
./src/Makefile.global:404:ifdef PROFILE
./src/Makefile.global:405:   CFLAGS += $(PROFILE)
./src/Makefile.global:406:   LDFLAGS += $(PROFILE)

I tried "make CC=cc PFOFILE=-pg", still segment fault.

I would love to debug it, but since release time is approaching, I'd
better share this possible bug ...
