Hi Nikolai,

Well, *I* don't but Ubuntu's (Debian's in reality, I guess) build system
does. :-)

CFLAGS="-g -O2 -fPIE -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security"
CXXFLAGS="-g -O2 -fPIE -fstack-protector --param=ssp-buffer-size=4 -Wformat -Wformat-security -Werror=format-security"

Interesting. I wonder if we can be more surgical and figure out which
one(s) are causing the problems? I suppose I can start though by
removing them all and seeing if that is my problem also.

Sadly, removing all CFLAGS/CXXFLAGS options done at configure time
didn't help:

I do notice at the end of the configure it reports:

configure: Multi-Language support enabled: yes
configure: BUILD LIBRARIES:
configure: BUILD EXTRA LIBRARIES: -lm -lnsl -lresolv -lrt -ldl -ldl
configure: BUILD OBJECTS:
configure: BUILD EXTRA OBJECTS:
configure: BUILD C FLAGS: -m64 -Wall
configure: BUILD EXTRA C FLAGS: -Wall -Wpointer-arith -Wwrite-strings -Wmissing-prototypes -Wmissing-declarations -Wcomments -Wshadow -Werror -pipe -D_REENTRANT

configure: BUILD EXTRA C++ FLAGS: -I/usr/include/libxml2 -Wall -Wpointer-arith -Wwrite-strings -Wcomments -Wshadow -Werror -pipe -D_REENTRANT

Those must be flags that configure has decided to add.
