| Summary | 0000119: par_conj/consume_wait test is failing in low-level C parallel grades. | ||||||||
| Description | The par_conj/consume_wait test is failing in low-level C parallel grades. I've tested this on goofy using the current CVS version and gcc 3.4. I don't remember noticing this on taura or goliath. | ||||||||

Somehow work-stealing fixes this test case failure. I still want to know why it was failing though, I'll continue investigating. |

There was a change some months ago to the dependent parallelism transformation that fixed a problem with the same symptoms. I think it's safe to close this bug and re-open it if the problem reoccurs. |
