Title:
Firefox crashes in flag_qsort during spellchecker initialization on
x86 due to gcc bug
Status in The Mozilla Firefox Browser:
Fix Released
Status in firefox package in Ubuntu:
Confirmed
Status in gcc-4.8 package in Ubuntu:
Incomplete
Bug description:
The most common Firefox crash on Linux in Mozilla's crash-stats system
is crashes in the function flag_qsort.
These crashes occur:
* only on x86 architecture
* only on Ubuntu packages (and not on Mozilla's builds)
* on precise and saucy and trusty (based on kernel versions reported with
the crashes)
and appear to be due to a compiler bug in the compiler used to generate
Ubuntu's builds. (It could be a common compiler bug triggered by different
compiler options or a compiler bug specific to Ubuntu's gcc.)
The analysis that leads to the conclusion that this is a compiler bug
is in https://bugzilla.mozilla.org/show_bug.cgi?id=983817 . In
particular, the compiler is miscompiling an access to an element of an
array of unsigned short as a 32-bit read, and when the unsigned short
in question is the last one in the allocation and that allocation is
aligned so that the byte following has a different 0x10 bit, this
can lead to crashes.

[Touch-packages] [Bug 1322784] Re: Firefox crashes in flag_qsort during spellchecker initialization on x86 due to gcc bug
It's an issue with something in the compilation toolchain that Ubuntu uses to compile the Firefox builds that Ubuntu ships.

[Touch-packages] [Bug 1322784] Re: Firefox crashes in flag_qsort during spellchecker initialization on x86 due to gcc bug
Actually, forget that - this bug isn't specific to gcc 4.8 anyway if it's occurring on precise. So, most definitely another issue.

We ought to be able to work around this, and probably should, given the lack of response. If somebody has a setup that can reproduce the compiler bug, there might be a straightforward workaround such as inserting |volatile| somewhere or similar trivial rearrangement of code. If not, we ought to be able to pad these arrays by 2 bytes, #ifdef linux and gcc. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gcc-4.8 in Ubuntu. https://bugs.launchpad.net/bugs/1322784 Title: Firefox crashes in flag_qsort during spellchecker initialization on x86 due to gcc bug Status in The Mozilla Firefox Browser: Confirmed Status in “firefox” package in Ubuntu: Confirmed Status in “gcc-4.8” package in Ubuntu: Confirmed Bug description: The most common Firefox crash on Linux in Mozilla's crash-stats system is crashes in the function flag_qsort.

Could somebody running the Firefox that has this crash (i.e., 32-bit Ubuntu packages) attach the contents of about:buildconfig to this bug?
