Meson 0.47.2 from Ubuntu 18.10 seems to work fine as-is in Ubuntu 18.04, so I
was able to do a Mesa built with a newer Meson version.
I'm still getting the assert though:
testfw_app: src/intel/common/gen_urb_config.c:152: gen_get_urb_config:
Assertion `total_needs <= urb_chunks' failed.
Then I tried Autotools build with --enable-debug.
It gives gives the same error, and additionally also:
Mesa: User error: GL_INVALID_ENUM in glGetString(GL_EXTENSIONS)
=> it's not a regression or Meson related, but an older issue on BSW.
This may actually explain <a class="bz_bug_link

I don't get assert with "release". As've I stated above, I was using
"debugoptimized".
FYI: I thought it corresponded to RELWITHDEBINFO target in CMake. With CMake,
there's the RELEASE build type that strips the binaries, and RELWITHDEBINFO,
which builds with debug symbols and doesn't do stripping i.e. binaries are 100%
match to release, just with debug info.
According to Meson docs, "release" build doesn't include debug symbols, but
according to "file" command it doesn't strip binaries either. Meson
documentation doesn't say anything about "debugoptimized" enabling asserts:
<a href="https://mesonbuild.com/Running-Meson.html">https://mesonbuild.com/Running-Meson.html</a>
So I'm not sure whether that's a bug or not.
=> With what Meson options I'm supposed to get Mesa binaries that correspond to
release build (no asserts), just with full (-g) debug symbols?
PS. IMHO Meson --help output or manual page should explain the differences
between the build targets. Currently it doesn't seem to be properly documented
even in latest Meson docs.</pre>
