I doubt we could ship next week's beta 78 with a crash of this magnitude

Severity: -- → S1
Summary: Crash in [@ mozilla::SandboxBroker::LaunchApp] → startup Crash in [@ mozilla::SandboxBroker::LaunchApp]
Version: unspecified → 78

Pretty sure this is the windows 100% startup crash Richard tracked down - from bug 1602832 (starting from the first patch there)

Regressed by: 1602832
Priority: -- → P1

Richard, are you able to verify that? Insert this before that line:

printf("xxx targetInfo=%d\n", !!targetInfo);

If it shows 0 this is the problem.

Alternatively, if this bug is about timing, could dllSvc be null?

Richard confirmed in matrix both targetInfo and dllSvc are ok.
I guess we're not getting the full stack then. Maybe it's failing at

OH, that is the case, the crash report says MOZ_CRASH Reason (Sanitized): MOZ_RELEASE_ASSERT(mInitDllBlocklistOOPFnPtr)

But I don't know why it's not on the stack.

Any idea what needs changing?

Any idea what needs changing?

I think we can disable socket process for Thunderbird before I figure out the root cause.

I think the proper way to fix this is calling DllServicesBase::EnableFull before launching socket process, but I have no idea why this is not called.

Could you also help to verify if disabling socket process can fix this crash?

I don't have a proper test setup for this myself, but Richard can reproduce and will check if this fixes it.

This patch works for me. TB starts again. Many thanks.

I updated TB daily just now , and recieved all times a crash.
I cannnot start or restart TB daily any more: creating a new profile doesnt help.

I downloaded thunderbird-79.0a1.en-US.win64.installer.exe (to install BuildID 20200604105934)
for updating from not startable Thunderbird 78.0a1, BuildID 20200528103753.
After Updating there was no mailprofile anymore but a error message at startup handled in bug 1643285 .
