Hello,

thanks for tracking that down.  I have verified that the segfault issue
also occurs when building on Ubuntu 16 x64.

Changing the command to:
*      ./configure_cmake.sh --prefix=/opt/snort --enable-tcmalloc
--disable-docs*
does not generate any errors and allows for successful build and
installation.

however, running snort3 when* -enable-tcmalloc *is included as above
generates a segfault;
   noah at snort18x:~/snort_src/snort3/build$* /opt/snort/bin/snort -V*
   Segmentation fault (core dumped)

Please let me know if any further info is needed.
thanks
Noah
