Subject: Can executable file(can't read) still be
	coredumped in solaris ?

hi ,dear friends:

I have tested succeed on solaris 8
Executable file(can't read) can be coredumped . 
Bug I don't know whether it is still exist or not.


[alert7@...aris8 solaris]$ uname -a
SunOS Solaris8 5.8 Generic_108528-29 sun4u sparc SUNW,Ultra-5_10

COREDUMP enable
example

[alert7@...aris8 alert7]$ ls -la test
--wx--x--x   1 root     pubcvs      6344 Aug 16 11:27 test
[alert7@...aris8 alert7]$ id
uid=108(alert7) gid=102(pubcvs)

[alert7@...aris8 alert7]$ ps -ef|grep test

[alert7@...aris8 alert7]$ kill -4 440
[alert7@...aris8 alert7]$ ./test ff

[alert7@...aris8 alert7]$ ls -la core

[alert7@...aris8 alert7]$ gdb -q -c core
Core was generated by `./test ff'.
Program terminated with signal 4, Illegal instruction.

these above signal also can cause process coredump if process not set signal handler
