Under FreeBSD, with clang and -O1, all works fine!!
Just a FYI: The configure script actually generates:
CFLAGS = -g -O2 -O1
which may eventually break builds. Want me to work on the configure.ac
patch?
I've done that yesterday to make clang work out of the box. The syntax
is correct AFAICS. Only the last -O flag is used by the compiler, the
rest is ignored.
However, I suspect that this problem can happen even if the library is
compiled with -O1 and user program is compiled with -O2. Which would
mean that the workaround above is not worth much.
Btw, I've done some investigation and so far it seems that the original
problem is actually a clang bug -- two simultaneous invocations of a
function report same addresses for local variables.
