FWIW, I've tried reducing the scope of this flag to bmalloc but the crash
was still there. However, passing it instead for WebCore only did "fix" the
situation, so perhaps the problem is not strictly related to bmalloc, but to
something else in the graphics subsystem?

I could also be a bug on GCC, though.
