This issue was originally filed by jack.palevich@gmail.com

What steps will reproduce the problem?

Unzip the attached file
dart fast.dart
Wait a second or so until the output gets to "linking row 118 of 300"

What is the expected output? What do you see instead?

Expected behavior:

The "linking..." messages to count up to 299, and then endless

current: XXX ms, max: YYY ms

messages will be printed. (It's a benchmark.)

Actual behavior:

The VM hangs after printing the "linking row 118 of 300" message. (It actually starts to slow down about 10 rows before then.)

What version of the product are you using? On what operating system?

Tip of bleeding edge circa November 26, 2011. Unfortunately dart --version doesn't work, so I can't be more specific.

The OS is Mac OS 10.6.8.

Please provide any additional information below.

This build is from:
dart/xcodebuild/Debug_ia32/dart , so it's a debug build of some sort.

We end up in back to back GC cycles, a fix for this is in the works.

In the meantime as a workaround please use the option --new_gen_heap_size=64

Added Area-VM, Triaged labels.
