What's the rest of the backtrace here? I assume there aren't any other STR besides "start up gecko-b2g build"?

This looks pretty bad ... crasher in an otherwise innocent-looking backtrace.

To build the "b2g product" for desktop, follow these instructions https://wiki.mozilla.org/Gaia/Hacking#Building_B2G

WORKSFORME on a MacBook AIR running OSX Lion. Pulled from hg (m-c) and github (gaia) today.

WORKSFORME on Linux x86-64.

I can give you access to my machine in the SF office.

Is this an optimized build? I'm seeing the same startup crash in an optimized build of Firefox (no b2g involved), but it doesn't happen in a debug build.

Both with XCode 4.2.1 and XCode 4.3.1 on OSX 10.7.

Building with clang leads to a working build. This would suggest a miscompilation with gcc in XCode > 4.1 (which is, I think, what i was using before upgrading).

For OS X 10.7.x, what are the best option for mozconfig then? We should put this on the wiki too if this is a known issue.

My understanding is that xcode > 4.1 don't have a real gcc-4.2 programs, instead using the gcc-4.2 frontend with an llvm backend. I'll try rebuilding OS X with clang

(In reply to John Ford [:jhford] from comment #17) > I'll try rebuilding OS X with clang And it worked, b2g launches. I can confirm that gcc on the system experiencing these issues is 'i686-apple-darwin11-llvm-gcc-4.2'

Homebrew? I found clang in /Developer/usr/bin/clang - I guess xcode installed it, and this worked for me by setting as described on https://wiki.mozilla.org/Gaia/Hacking. In case it helps someone, my crash was slightly different to the one above ( I had RIL support disabled): Program received signal EXC_BAD_ACCESS, Could not access memory.

Homebrew? newer Xcode versions have a version of clang/clang++ on the standard path. To build with clang, I ran export CC=clang export CXX=clang++ before make -f client.mk build, but this could easily be inside of your mozconfig.

Thanks - a while ago I had ditched XCode in favour of Apple's smaller basic compiler package - looks like I need to go back.

Confirmed: installed latest Xcode and set CC/CXX to clang as above, desktop build now works fine.

fyi, /usr/bin/gcc is a softlink to llvm-gcc... you can delete the softlink and link it to the /usr/local/bin/gcc-4.6
