Samba was configured:
./configure --prefix=/opt/samba3 --enable-cups --with-sys-quotas --with-utmp
--with-acl-support
CFLAGS were "-O2", 
OS is:
SuSE9.2 on AMD X86_64.
Samba3.0.14a runs flawlessly with same configure parameters.
Comment 1 Volker Lendecke 2005-07-25 03:54:02 UTC
Could you retry without optimization? I hit this bug on SLES9 SP1, upgrading to
SP2 or compiling without optimization helped here. I *very* stronly assume a
compiler bug, as with other gcc options and version it works fine.

Closing this bug, it is very probably not ours. Please reopen if it still
persists without -O.

Hi Volker,
my steps were now as follows:
make distclean
export CFLAGS="-O"
./configure --prefix=/opt/samba3 --enable-cups --with-sys-quotas --with-utmp
--with-acl-support && make && make install
I still get the same error. It's quite unlikely that I am the only one, so I
must have been done something wrong. On the other hand, the same procedure
worked since samba2.2.x and I rarely leave out any pre-alphas ;-)
Should I rather post this to the samba-mailing list?

Sincerely,
Malte
Comment 3 Gerald (Jerry) Carter 2005-07-27 06:54:35 UTC
please verify that the CFLAGSin the generated Makefile match what
you set in the environment.
Comment 4 Gerald (Jerry) Carter 2005-08-15 11:40:33 UTC
verified as gcc bug.  -O is the same thing as -O1.
Comment 5 Gerald (Jerry) Carter 2005-08-15 11:40:47 UTC
should have been marked as invalid.
Comment 6 Gerald (Jerry) Carter 2005-08-15 11:41:00 UTC
closing for real now.
