Latest chromium-dev build fails with error: enumerator value '-1' is outside the range of underlying type 'size_t' {aka 'long unsigned int'}

Hi,

The last two chromium-dev builds are failing to build on openSUSE. This was caused by the latest addition of base/containers/intrusive_heap.h.

The error message is:

[ 397s] In file included from ../../base/task/common/intrusive_heap.h:8,
[ 397s] from ../../base/task/sequence_manager/task_queue_impl.h:19,

[ 397s] ../../base/containers/intrusive_heap.h:460:58: note: (if this is not what you intended, make sure the function template has already been declared and add <> after the function name here)

It sounds logical to me that when I have an unsigned int, that I can not assign the value -1 to it :)

Thanks
