This pull request adds flags for ASAN, MSAN and UBSAN as well as configures gdb to follow forks, making debugging WebContent with ninja debug a bit nicer

Is there a way to make MSAN ignore Qt?

Is there a way to make MSAN ignore Qt?

What kind of errors are you seeing from MSAN? (And are you sure it's not LeakSanitizer?)

networkException commented 2 years ago

MemorySanitizer: use-of-uninitialized-value (Well it says MSAN on the box)

ADKaster commented 2 years ago

Ah, that sounds like the sort of thing valgrind would catch too. If it's reported by both then we should see if it's originating from a value we passed in. It's also possible there's suppressions in valgrind that we'd have to replicate.

Valgrind catches other things that don't look necessarily related but at least that doesn't cause the process to crash
