## Regression Testing Notes

### Note 0

This test fails only intermittently.

### Note 1

The failure is caused by a problem in Boost code. The Boost developer is aware of the problem and plans to fix it.

### Note 2

The failure is caused by a compiler bug.

### Note 3

The failure is caused by a compiler bug, which has been reported to the compiler supplier (or is already known to them).

### Note 4

The failure is caused by a standard library bug.

### Note 5

The failure is caused by a standard library bug, which has been reported to the standard library supplier (or is already known to them).

### Note 6

The failure is probably caused by the test code, harness, or configuration. Thus it may not affect users of the library.

### Note 9

The failure is serious and likely to prevent all use of this Boost library with this compiler.

### Note 10

The failure is serious and likely to prevent all use of this Boost library with this compiler. The failure is caused by a compiler bug, which has been reported to the compiler supplier (or is already known to them).

### Note 14

The failure is caused by a platform API bug.

### Note 15

The failure is caused by a platform API bug, which has been reported to the platform API supplier (or is already known to them).

### Note 16

The failure is not serious and will not affect most users. The library degrades gracefully.

### Note 17

This compiler's bugs are not supported by the library.
