Let me apologize in advance for sending this to the wrong places |
| 2 |
rather that submitting a bug report. I don't know where the bug is, |
| 3 |
and I an double-posting because I am not sure this isn't SPARC specific. |

1. If you give mozilla complete garbage to display, |
| 9 |
sometimes it fills the screen with garbage, and sometimes |
| 10 |
it exits silently. This is with the SAME garbage --- |
| 11 |

http://gentoo.oregonstate.edu/experimental/sparc/livecd/sparc64/ |
| 13 |
gentoo-sparc64-1.4_rc4-08Sep2003-cd1.iso |
| 14 |
will do. |
| 15 |
2. Same with mozilla-firebird, except it provides "Illegal Instruction" |
| 16 |
as a clue (to buffer overrun?) |
| 17 |

As above, plus the following: |
| 21 |
3. Systems involved are sparc U2(lacewing), U60(antaresia) with |
| 22 |
identical kernels 2.4.21-r1(SMP) |
| 23 |
4. mozilla is " [ I] net-www/mozilla-1.4-r3 (0)" (current for sparc) |
| 24 |
5. mozilla-firebird is "[M~I] net-www/mozilla-firebird-0.7 (0)" |
| 25 |
otherwise running pretty much flawlessly. |
| 26 |
6. xfree on U2 is "[ I] x11-base/xfree-4.3.0-r3 (0)" (current for |
| 27 |
sparc) |
| 28 |
7. U60 has two root partitions. One is an exact clone of the other (as |
| 29 |
of 13 November) except for xfree-4.3.0-r2. Behavior is |
| 30 |
non-deterministic with either partition mounted on "/". |
| 31 |
8. All xfree versions have xfree patched (as per comments #32, 33 to |
| 32 |
bug 19776 because for me xfree is otherwise unusable.) |
| 33 |
9. Except for today's invitation to update glibc, both systems are |
| 34 |
completely current and rock solid. |
| 35 |
|
| 36 |
Observations: |
| 37 |
------------- |
| 38 |
10. On a third system (U2-SMP, terciopelo), problem is less likely to |
| 39 |
occur (maybe |
| 40 |
never, but I haven't sat at it displaying garbage over and over). |
| 41 |
It started out as a clone of the original U2, and is current, |
| 42 |
but I cannot guarantee that its software configuration is |
| 43 |
identical to the original U2 (lacewing). |
| 44 |
11. The U2(lacewing) and U60(antaresia) are not identically configured |
| 45 |
(hardware or software packages.) |
| 46 |
12. Empirically, -root- has a slightly better chance of success than |
| 47 |
I as me do. |
| 48 |
13. Empirically, it seems to help if you try to list a '.bz2' file |
| 49 |
first; both mozillas filter that out as something they can't deal |
| 50 |
with and ask for help, but then seem more likely to display |
| 51 |
garbage for the '.iso' file. |
| 52 |
14. The "Illegal instruction" makes this look like a buffer overrun or |
| 53 |
otherwise an attempt to execute data or a program which isn't |
| 54 |
loaded yet. |
| 55 |
15. Note that mozilla looks to be pretty agressively threaded. |
| 56 |
16. For me, gdb has problems with mozilla. |
| 57 |
17. Oh, before you ask: The mozilla ebuilds downgrade the CFLAGS for |
| 58 |
mozilla to "-mcpu=v8 -mtune=ultrasparc" so there should be no |
| 59 |
sparc64 issues here nor similar "-cpu=v9" questions. |
| 60 |
18. No, I don't use any font server. |
| 61 |
19. I doubt that this is related to xfree-4.3.0-r3's cryptic "If |
| 62 |
you have font problems with openoffice, regenerate XF86Config" |
| 63 |
advice, because: |
| 64 |
a. xfree-4.3.0-r2 seems to exhibit the same behavior; |
| 65 |
b. And I couldn't act on that advice anyway, because it doesn't |
| 66 |
give a clue how one should change XF86Config. |
| 67 |
---------------- |
| 68 |
|
| 69 |
By no means do I reject the possibility that this is a problem of my |
| 70 |
own creation. But if it is such a thing, I do not see how it does not |
| 71 |
stem from poor interaction among otherwise benign packages. (I say this |
| 72 |
so that I am more likely to see what I've screwed up immediately after |
| 73 |
sending this, so that I'll have to come back and admit my mistakes :-) ) |
| 74 |
|
| 75 |
I suppose I am asking for suggestions on how you (collectively) would |
| 76 |
like me to proceed. I am not really in a position to track down what look |
| 77 |
to me like (possibly sparc only) timing problems between mozilla and ?? |
| 78 |
which cause mozilla silently to give up. |
| 79 |

Sorry for going on so long, |
| 81 |
