Rebuilding the FreeCAD-wasm PySide binding stack with NATIVE wasm exceptions (new-EH / try_table, -fwasm-exceptions -sWASM_LEGACY_EXCEPTIONS=0) to match the JSPI + wasm-EH toolchain (qt-jspi is try_table). Mixed EH => invalid module, so EVERY C++ archive must be new-EH with ZERO 'U invoke_' symbols. Env: source /opt/toolchains/emsdk/emsdk_env.sh AND export LD_LIBRARY_PATH=/home/magik6k/lcad-wasm/pyside-port/libshim (host shiboken6 needs the libclang shim). Working dir /home/magik6k/lcad-wasm/pyside-port. The build scripts there ALREADY have the new-EH flags applied. QtCore was already rebuilt new-EH (build/m2-qtcore/, validated). VERIFY each output archive: (a) it exists + has its PyInit symbol; (b) new-EH: emnm <archive> | grep -c 'U invoke_' MUST be 0 (invoke_ = JS-EH leftover = fail); (c) optional: extract one .o, link 'int main(){}' + the .o with 'em++ -fwasm-exceptions -sWASM_LEGACY_EXCEPTIONS=0 -sJSPI -sERROR_ON_UNDEFINED_SYMBOLS=0' and node -e 'WebAssembly.validate(...)' == true. Report the archive path, PyInit symbol presence, invoke_ count (must be 0), and pass/fail. REBUILD the GL-select stubs new-EH. Run: cd /home/magik6k/lcad-wasm/pyside-port/build/glstubs && source /opt/toolchains/emsdk/emsdk_env.sh && em++ -fwasm-exceptions -sWASM_LEGACY_EXCEPTIONS=0 -O2 -c glselect_stubs.cpp -o glselect_stubs.o && emar rcs libglselect_stubs_wasm.a glselect_stubs.o. VERIFY the 6 gl* symbols present (emnm | grep 'T gl') + 0 invoke_. Report.

I'm starting with the GL-select stubs rebuild task for new-EH, then I'll verify the results.

I'm checking the count of gl* symbols and invoke_ calls to verify they match expectations.

All the GL symbols are present and there are no invoke calls, so the build succeeded. I'm not entirely sure what invokeCount refers to, but it's likely tracking the number of invoke_ calls, which is zero, so I'll set invokeCount to 0 and report the results.
Fable
All verifications pass. Reporting.
