GC garbage collector

Macaulay2 uses the excellent garbage collector GC, version 7.2 alpha 6, written by Hans-J. Boehm and Alan J. Demers and generously licensed to the public. It is available at http://www.hpl.hp.com/personal/Hans_Boehm/gc/.

Some environment variables can be set by the user to tune garbage collector performance:

The full list is found in the source code for gc in the file doc/README.environment.

Here are some error messages you may see from it when it aborts the program, due to lack of memory or related problems. Typically, the only recourse for the user is to increase the memory available to the program.
