I alluded to this issue earlier. Upgrading *only emsdk-portable* from
1.37.36 to 1.38.11 and keeping everything else the same results in a
wasm file that won't start. Further, its size is ~2.4M whereas the size
under 1.37.36 is just over 10M. I'm using Rust nightly, cargo-web and
the wasm32-unknown-emscripten target. All needed dependencies are
rebuilt under 1.38.11 before rebuilding the Rust binary. _main is
definitely specified in the list of exported functions. Here are my
linker arguments as passed to rustc:
link-args = [
"-s", "ASSERTIONS=1",
"-L", "vendor/prefix/lib",
"-l", "proj",
"-l", "geos_c",
"-l", "geos",
"-l", "z",
"-s", "EXTRA_EXPORTED_RUNTIME_METHODS=['ccall','cwrap']",
"-s", """EXPORTED_FUNCTIONS=[
'_spatialite_version',
'_spatialite_alloc_connection'

]"""
]
Is there any known issue between 1.37.36 and 1.38.11 that might have an
effect here? How do I even go about debugging this? I have an older copy
of the intermediate Rust artifacts, including the final .wasm file.
Thanks for any help.
