I think it's mandatory to compile with '-fPic', if compiling with '-pie' on amd64 processors. Please add it to the configure options.

If you look at the OPTIM definition, you'll find both -fpie and -fPIC.

The issue appears to be that the DSO flags don't include -pie, however that brings up an issue of the pthreads library which apparently needs to be explicitly listed with -pie, but not normally...

I'll see what I can do to get things to compile with --enable-pie, but it isn't something we normally build or test with...

OK, I just committed a fix for this in r5466. Please let me know if that doesn't fix things for you...

Yes, it fixes the problem.
You might want to close this STR. :-)
