Hi,

Preloading Mesh for root.exe from https://github.com/root-project/root/ causes

$ LD_PRELOAD=./bazel-bin/src/libmesh.so root.exe -l -b -q

segfault (1/0xffffffff): in arena? 0

That's with Mesh's master from 1h ago on Ubuntu 20.04.1.

ROOT is using cling and its llvm-jitting and I was guessing that this might cause havoc - but that's not it: Mesh works with cling like a charm!

LD_PRELOADing jemalloc works for ROOT:

$ LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.2 root.exe -l -b -q
$

So how would I go about debugging this? Do you have instructions on how to get a Mesh build with debug symbols, are there assertions I should be turning on, etc?

(I bet the CERN LHC experiments' software stacks will love to try this out once we manage to get Mesh to work with ROOT!)

Cheers, Axel.
