[GNATS 21720] Boost test runs out of memory

[jhsedg]

Customer bug ID

(boost) csundef (3 tests ) gnats/_21720.C (full expanded test).

Description

​This series of Boost tests runs out of memory. The -d-spaced_used does not work, so this is a snapshot from gdb.
​
​The full test is in the gnats/_21720.C

​
​This test doesn't seem to run out of memory, but does take an inordinate amount of time (about 17 minutes on lin6). Also, g++810 doesn't compile it:
