Comment (by rhaas):

 When trying this with gcc (4.6) I needed to #include <cstring>. I also
 added code to output the backtrace.xx,txt files to out_dir in case more
 than one run segfaults. Finally I seem to require -ldl in LDFLAGS
 otherwise it fails during link time with dladdr not found. -lcrypto (from
 OpenSSL) also allows me to link (I assume crypto links to dl), so maybe
 this never happened with the ET thorn lists. Since dladdr is not POSIX but
 a GNU extension, is there maybe an autoconf test for it? I have never used
 autoconf myself so have no idea.
