[Octave-bug-tracker] [bug #61821] segfault using tree_parameter_list in oct file

[Markus Mützel]

Follow-up Comment #11, bug #61821 (project octave):

Thank you for hunting this down.

Just to give some background: The "official" Octave for Windows isn't compiled
with the compiler that is included in its installation. Instead, it is
cross-compiled on Linux with a cross-compiler that is built in the packaging
process by MXE Octave. [1]
The compiler that is bundled with Octave for Windows is also cross-compiled on
Linux (for a mingw host and target).

There is another version of Octave that is built natively on Windows (e.g.
using the tools of the MINGW32 environment) as part of the MSYS2 project. [2]
That is pretty new. And tbh, we didn't get much feedback for that version
yet.
That project also uses GCC. But the build tools and compiler version and
configuration might be different. And maybe that bug only occurs when Octave
was cross-compiled.
If you are interested, maybe you could test if that version of Octave on
Windows also exhibits that strange behavior for 32-bit.

The version currently distributed by MSYS2 is Octave 6.4.0. But you could try
with the build artifacts of the first release candidate. [3]
