Hi monks, I am seeing much larger sizes for XS .so files when building under x86_64 versus i686.

E.g. smaps reports a size of 2085 kB for lib/perl5/x86_64-linux-thread-multi/auto/Time/HiRes/HiRes.so
versus a size of 24 kB for lib/perl5/i686-linux/auto/Time/HiRes/HiRes.so

In fact, all of the x86_64 .so files are > 2000 kB.

Is there some common problem I am tripping up on?

OS is Centos 5.5 (5.4 for i686), perl version is 5.12.2. My Configure invocation for x86_64 is: 

 ./Configure            \
-des                     \
"-Doptimize=-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -f
+stack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic" \
