---------------------------------------------------------------
Things we have tried, in an attempt to work around or fix this:
i. Moved the {code}regex{code} variable declaration out of
`HostStatSampler::forEachIndexStatFile` to see if it made any difference
ii. Simplified the `regex` to make sure it wasn't the string expression passed
in that was blowing up
iii. Made `HostStatSampler::forEachIndexStatFile` a regular method taking an
`std::function` parameter, rather than a template
iv. Turned off all compiler optimization (`-O0`), for the individual function,
then file, then entire code base
v. Added the same `regex` variable to the test code, to see if it only blows up
in library code, as opposed to app code. Spoiler alert: no
We are now in the process of investigation the following potential fixes:
vi. Figure out what compiler/tool/library(ies) were updated when we last built
our RHEL-8 image, and see if we can roll back
vii. Switch from `std::regex` to `boost::regex` to see if boost has the same
problem
