You need a newer compiler (gcc 4.7 at least, newer versions are better).

Ramin,

First of all, you should add -fsanitize=address to CFLAGS, CXXFLAGS and LDFLAGS.

If that does not help, you'll need to investigate why compiler test
inside configure fails. You can find particular source code and
command line options which cause your g++ compilation to abort in
config.log.

i don't know, i spend many time for resolve it, but nothing,


so i use : ./configure --disable-shared CFLAGS="-fsanitize=address -ggdb" CXXFLAGS="-fsanitize=address -ggdb"

again i got error:

c++: error: unrecognized command line option '-fsanitize=address'

The instructions aren't quite correct, they miss the LDFLAGS setting.
I emailed Hanno, not sure when he fixes this.

Please try to execute
gcc --version
g++ --version
c++ --version
and report your findings.

For some reason configure script has different opinion on this, it
seems to use an older version:
c++: error: unrecognized command line option '-fsanitize=address'
To understand what's going on, you probly need to inspect config.log
and see which command is failing and why.
