[issue6673] Uncaught comprehension SyntaxError eats up all memory

[Terry J. Reedy]

Terry J. Reedy <tjreedy at udel.edu> added the comment:

With 32bit winxp Windows Task Manager open to Processes, sorted by Men Usage, I verified expanding memory usage in 3.2.0 (and stopped at 200 mb versus normal <20Mb). While we do not expect compiler to catch while True: pass, it would be nice if this was, with a reasonable error message.

No one marked for 2.7 because behavior only occurs with genexp and Nick says not so clearly a SyntaxError.
