[spam][crazy] Diagnosing an Explosive Failure

[k]

My example doesn't reproduce it, but this does:

git clone --depth=1 https://github.com/pytorch/pytorch
git clone --branch vmem-wip https://github.com/xloem/mimalloc
cd mimalloc
cmake .
make
LD_PRELOAD=$(pwd)/libmimalloc.so VMEM_PREFIX=vmem cmake ../pytorch

cmake on the pytorch folder sends out the SIGKILLs.  just a vanilla
'cmake' does not.
