ARM symbols not available on crash-stats.mozilla.com when Firefox crashes

[Henri Sivonen]

When Firefox crashes on Ubuntu on ARMv7, it offers to report the crash to Mozilla, which is good, but Mozilla's crash reporting system appears to be unable to extract symbols for a stack trace.

See e.g. https://crash-stats.mozilla.com/report/index/c6aa6dc1-90f3-44ec-8f7f-337f72160813

I'm guessing that whatever process is used to upload symbols for Ubuntu's x86/x86_64 builds to Mozilla's server is not being followed for ARMv7. Please make the ARM symbols available to Mozilla for more useful crash reporting.

Not uploading symbols for Arm is deliberate, given that it's a tier 3 platform. I think the bug here is that the crash reporter is enabled at all.

Wouldn't it make more sense to upload the symbols to let people who care diagnose bugs but not include ARM crashes in Mozilla's crash statistics?

[Henri Sivonen (hsivonen)]

As a user who might be able to fix the crash, having a crash stack show up without building a debug build myself is more important than on x86_64, because my Raspberry Pi 3 doesn't have enough RAM to link libxul, so just making a debug build on my own and running it under gdb when it crashes doesn't work.
