PPT sample
This is an assertion failure, and only occurs in builds where those are
enabled, typically debug builds.
Open attached PPT in LO, and save it as PPTX.
-> You get:
Assertion failed: iter != maPlaceholderShapeToIndexMap.end(), file
D:/sources/libreoffice/sd/source/filter/eppt/pptx-epptooxml.cxx, line 2484
Observed using a debug build of 25.8.0.0.alpha0+
(6042e60d69c40d1f307710e60a278cb286d68603) / Windows.
The assert is in the following line:
https://opengrok.libreoffice.org/xref/core/sd/source/filter/eppt/pptx-epptooxml.cxx?r=76c6d180f398a7d482665c24c07ec75f8a1dc7cd#2484
And was added in the following commit on 2023-12-04:

I don't know if it's related, but in a daily build (non-debug), when saving the
PPTX to PPT, the result is occasionally corrupted, PowerPoint can't open it.
Interestingly, I've only encountered that with manual open/save, if I do
--convert-to, the result could always be opened in PowerPoint. It might be
worth checking separately, but only after this assertion failure is gone.
