loadModuleFromSource() causes assertion failure on Ubuntu

[rob271]

I get a runtime assertion failure unless I replace:
Slang::ComPtr<slang::IModule> slangModule{ slangSession->loadModuleFromSource("triangle", "assets/shader.slang", nullptr, nullptr) };

with this line:
Slang::ComPtr<slang::IModule> slangModule{ slangSession->loadModule( "assets/shader.slang", nullptr) };

Using diagnostics it gives me this: assert failure: slang-session.cpp(56): blob

I'm not sure whether this is expected behavior on Linux or whether there is something specific about my configuration that I'm missing. Anyway, I just wanted to report this in case this information is useful for someone.

Environment:
Ubuntu 24.04.4
Vulkan SDK 1.4.357.1
GCC 14
GLM 1.0.3
SDL3 3.2.31
Slang 2026.13.1-1-g84792eb15

I'm aware and already looking into it.

And no, this is not expected behaviour and only happens with newer Slang versions.

This is an error on current Slang releases, including the one shipping with the most recent SDK.

See shader-slang/slang#12852

This is fixed with the next Slang release (not yet available).
