Bug Description

Binary package hint: xulrunner-1.9.1

gcc produces a crashing xpidl when building firefox on powerpc with -Os

with -O2 this doesn't happen as it seems.

asm Code failing is pasted below and http://mxr.mozilla.org/mozilla1.9.1/source/xpcom/reflect/xptcall/src/md/unix/xptcstubs_ppc64_linux.cpp

// gcc-3 version
//
// As G++3 ABI contains the length of the functionname in the mangled
// name, it is difficult to get a generic assembler mechanism like
// in the G++ 2.95 case.
// Create names would be like:
// _ZN14nsXPTCStubBase5Stub1Ev
// _ZN14nsXPTCStubBase6Stub12Ev
// _ZN14nsXPTCStubBase7Stub123Ev
// _ZN14nsXPTCStubBase8Stub1234Ev
// etc.
// Use assembler directives to get the names right...

This bug was fixed in the package xulrunner-1.9.1 - 1.9.1.3+build1+nobinonly-0ubuntu3

---------------
xulrunner-1.9.1 (1.9.1.3+build1+nobinonly-0ubuntu3) karmic; urgency=low

  * workaround LP: #411439 - build failure on sparc; we disable jit on sparc until
    bmo 502369 is really fixed for us
    - update debian/rules
  * workaround LP: #435560 - xpidl binary produced by gcc 4.4 crashes on
    powerpc if built using -Os optimization; we force -O2 on powerpc to
    workaround this
    - update debian/rules
  * require libwi-dev >= 29-2ubuntu6 for powerpc and sparc as it contains fixes
    for such long double 128 support archs. See LP: #435793
    - update debian/control
