Confirmed. The problem appears with gcc-3.4.4-r1 (stable branch) and |
| 28 |
both, vanilla-sources 2.4.30 (stable) and 2.4.32 (testing). |

I compiled everything with gcc-2.96 on a |

Problem: |
| 34 |
I think the problem is the way in which gcc-3.4.4 manage recursive |
| 35 |
inlining. sg_fill is an inline function which call itself and 3.4.4 |
| 36 |
doesn't like that. |

We have our gcc ninjas working on it, hope to have it fixed soon. |

|
| 41 |
Workaround: |
| 42 |
I think is only problem of gcc-3.4.4. I can compile it with gcc-3.3.2 |
| 43 |
just fine. Since gcc is installed slotted, probably everyone who updated |
| 44 |
the gcc compiler can change it using gcc-config and compile the kernel |
| 45 |
with an old gcc (if needed). |

Thanks guys for reporting. |
