I can't reproduce this using newly built VMs.  I can't run the VM supplied
because my 64-bit CentOS 6.5 has globe v 2.12 and the VM you reference
requires 2.15.  I built form the sources I've just pushed.  here's the
version info:

~/oscogvm/products/sqcogspur64linux/squeak -version
5.0-201704270225  Wed Apr 26 19:29:45 PDT 2017 gcc 4.4.7 [Production Spur

It's probably not the answer you're looking for but either try the latest
VMs from binary (built from 201704270225) or I could package up the 64-bit
VMs I've built and put them e.g. on the cogblog ftp server for you to use.
If the bintray VMs crash and mine don't that points to an issue with the
build environment or perhaps with gcc 4.6.x vs the 4.4.x I'm using.
