[Snort-devel] Segfault building Snort3 b245 with --enable-tcmalloc flag

Interesting. Snort build 245 with tcmalloc over CetnOS 7 and FreeBSD 11 was successful. There have been recent changes in Ubuntu 18 that are making several apps too unhappy. I will do some testing on my side and report back if I come up with anything useful.

when building Snort 3 245 with the --enable-tcmalloc flag, snort throws a segfault.

Environment: git clone of the latest Snort3 (b245) on Ubuntu 18 x64 in a VMware virtual Machine.

cd ~/snort_src
git clone https://github.com/snort3/snort3.git
cd ./snort3
./configure_cmake.sh --prefix=/usr/local  --enable-tcmalloc
cd build

When you remove the --enable-tcmalloc flag, snort compiles and runs without error:
