Firefox 6.0 at Natty still has this issue as the patch is not yet applied. Also confirmed that this is already included at the 7.X version available for Oneiric, so once the 7 release is backported to Natty, this should be officially fixed.

Chris, how do you usually proceed when a patch is already available upstream but needs backporting for a previous Ubuntu version, like Natty?

[Bug 789198] Re: Firefox crashes when attempting to play webm video on ARM with Thumb2 enabled
It would be interesting to try building the assembler code in Thumb since that would also fix this problem, but the code isn't 100% ready yet. There are some bits that are not Thumb-ready (e.g., MOV pc, lr instead of BX lr), and because the assembler is invoked separately, .thumb, .syntax unified and .type symblol, %function directives would be needed to make that work.

wrong alignment to be set for code sections -- upstream binutils bug
raised and cross-referenced from this bug.
When building firefox for Thumb, .text contains a mixture of Thumb code
and ARM code (the ARM code comes from the */arm/*.asm files). The ARM
code sections don't declare an appropriate alignment requirement in the
objects output from the assembler, and end up in the final link aligned
on an odd halfword offset.
Disassembling /usr/lib/firefox-5.0/libxul.so shows the boundary between
compiler-generated Thumb code and the hand-written ARM assembler, with
the ARM instructions on an invalid, non-word-aligned offset:
61e6f2: 9201str r2, [sp, #4]
61e6f4: 6a5aldr r2, [r3, #36] ; 0x24
61e6f6: 695bldr r3, [r3, #20]
61e6f8: f42f efd0 blx 24e69c _init+0x5da4
61e6fc: bd0epop {r1, r2, r3, pc}
0061e6fe vp8_decode_mb_tokens_v6:
61e6fe: e92d4ff0push{r4, r5, r6, r7, r8, r9, sl, fp, lr}

Currently the output section alignment is often left untouched, which may result in invalid alignment when sections are merged at link-time. This appears to be responsible for a faulty WebM codec behaviour when firefox-5 is built in Thumb, as a result of ARM code being linked into .text alongside Thumb code. The ARM instructions are placed at halfword alignment and so can't be executed correctly. I don't know if this is a recent regression or an older bug. It appears present in trunk as of 2011-06-24. The bug is also present in linaro binutils 2.21.0.20110327-2ubuntu2cross1.62 In both of the cases below, the .text section alignment should not be 2**0. The alignment should probably be set to 2**2 (though it could in principle be 2**1 for some Thumb code, some Thumb instructions are alignment-sensitive modulo 1 word; the 16-bit PC-relative add and ldr instructions have this restriction). $ cat EOF tst-align.s .type f, %function .globl f f: nop EOF $ arm-linux-gnueabi-as -o tst-align.o tst-align.s $ arm-linux-gnueabi-objdump -hd tst-align.o tst-align.o: file format elf32-littlearm Sections: Idx Name Size VMA LMA File off Algn 0 .text 0004 0034 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE 1 .data 0038 2**0 CONTENTS, ALLOC, LOAD, DATA 2 .bss 0038 2**0 ALLOC 3 .ARM.attributes 0016 0038 2**0 CONTENTS, READONLY Disassembly of section .text: f: 0: e1a0nop ; (mov r0, r0) $ arm-linux-gnueabi-as mthumb $ arm-linux-gnueabi-objdump -hd tst-align.o tst-align.o: file format elf32-littlearm Sections: Idx Name Size VMA LMA File off Algn 0 .text 0002 0034 2**0 CONTENTS, ALLOC, LOAD, READONLY, CODE 1 .data 0036 2**0 CONTENTS, ALLOC, LOAD, DATA 2 .bss 0036 2**0 ALLOC 3 .ARM.attributes 0016 0036 2**0 CONTENTS, READONLY Disassembly of section .text: f: 0: 46c0nop ; (mov r8, r8) Reply at: https://bugs.launchpad.net/binutils/+bug/789198/comments/18 On 2011-06-24T19:30:19+00:00 Dave Martin wrote: For details of the Firefox/WebM bug, see: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/789198 Reply at: https://bugs.launchpad.net/binutils/+bug/789198/comments/19 ** Changed in: binutils Status: Unknown = Confirmed ** Changed in: binutils Importance: Unknown = Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/789198 Title: Firefox crashes when attempting to play webm video on ARM with Thumb2 enabled To manage notifications about this bug go to: https://bugs.launchpad.net/binutils/+bug/789198/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Great Dave, I'm building firefox with the potential workaround described by you and should have the results in a few hours. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/789198 Title: Firefox crashes when attempting to play webm video on ARM with Thumb2 enabled To manage notifications about this bug go to: https://bugs.launchpad.net/binutils/+bug/789198/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
