This error doesn't happen on X11 using the mesa master branch. Instead,
I get the following error on that branch:
../src/gallium/drivers/freedreno/freedreno_batch.c:424:fd_batch_add_dep:
Assertion `!batch_depends_on(dep, batch)' failed.
Full disclosure though: I rebuilt the mesa package using the
postmarketOS packaging yesterday and it includes a few extra patches for
musl libc.
https://gitlab.com/postmarketOS/pmaports/tree/master/temp/mesa
I don't see anything obvious in those patches that would be related..
but I suspect this type of error is going to be timing related.
(Which could ofc be due to musl or something else)
but a bit surprised debug_assert() is enabled in debug builds.. it
would probably be a "harmless" situation if asserts were not enabled.
(note that I do most of my testing with debug builds with asserts
enabled.. this is the type of thing that I want to see and fix.. but
probably shouldn't matter to end users)
I recompiled the master branch of mesa in pmOS with '-Db_ndebug=true'
and X11 is now working properly on the Nexus 5. glxgears averages about
59.5 FPS. I'll add a bug report with pmOS to have them add that flag to
their mesa build. Fedora added that flag to their builds:
https://bugzilla.redhat.com/show_bug.cgi?id=1692426
19.1.0-rc5 still doesn't work for me due to the original error.

You probably want '--buildtype=release' instead of '-Db_ndebug=true'
According to:
https://gitlab.freedesktop.org/mesa/mesa/blob/master/docs/meson.html#L321
-Db_ndebug - This option controls assertions in meson projects. When
set to false (the default) assertions are enabled, when set to true
they are disabled. This is unrelated to the buildtype; setting the
latter to release will not turn off assertions.
Brian
I always thought release == no assertions, I guess meson has different
ideas. You will want '--buildtype=release' anyway for optimizations, etc.
