fdo58197-1.pptx will do fine to reproduce it, they're all the same
issue.

It crashes in libxmlreaderlo.so because an unexpected std::length_error
exception is thrown and it dies through std::terminate. My commit
"fixes" this by making those methods allow std::exception derived
exceptions to be thrown through them, so it doesn't crash.

if you...

gdb --args ./instdir/program/soffice.bin --headless --convert-to pdf
fdo58197-1.pptx
(gdb) catch throw std::length_error
(gdb) run
(gdb) up... a bunch of times until you get to chartconverter.cxx

you'll see that chartconverter.cxx:136 is
Matrix< Any > aMatrix( rDataSeq.mnPointCount, 1 )
and rDataSeq.mnPointCount is -1, which doesn't make sense as a length
argument to vector::resize
