Thanx for an interesting report.
There may exists a bug in rdu_buf_lock().
Other than CFLAGS, you need to set LDFLAGS. Probably "INSTALL" or
"Install" too.
In Makefile, LDFLAGS is set as
${LibSo}.${LibSoMajor}.${LibSoMinor}: override LDFLAGS += -s
This '-s' means to strip.
And "Install" is
Install = ${INSTALL} -o root -g root -p
"INSTALL" is set by make(1) and it may be set -s/--strip option on your
system. But you will find out easily if you look 'make's output
carefully.
Also you may want to add -UNDEBUG to CPPFLAGS, in order to enable the
assertions for the debugging purpose.
How do you set your LIBAU environment variable? Usually it is set as
"all".
