Hi, All

Thanks for the help on this thread.

After some investigations, and I found that that the big difference is
caused by that flounder uses demalloc in the implementation,
and flo uses jemalloc implementation.

Thanks,
Yongqin Liu

      You probably can use the option &quot;showcommands&quot; to see there is \
any<br>  difference during the compile/strip process.<br>
<br>
I compared the output, there is no big difference except the following 2 header<br>
files paths specified for flo platfomr:<br>
<br>
      -isystem device/asus/flo/kernel-headers -isystem<br>
      hardware/qcom/msm8960/kernel-headers<br>
<br>
<br>
I don&#39;t think these options make the difference.<br>
<br>
nexus9.txt is the output for flounder platform.<br>
nexus7.txt is the output for the flo platform.<br>
<br>

            The binaries are 32bit static linked version compiled with the \

<br>
My 2 cents:<br>
Is it possible that you dump the build command of libc.so for flo and flounder?<br>
For your build log, flo is 32bit android while flounder is 64bit. 32bit libc<br>
64bit android is built as 2nd arch. It may be something different there.<br>
