Public bug reported:

mkvtoolnix is currently FTBFSing on impish because of LTO:

...
g++-9 -fstack-protector-strong -Wl,-Bsymbolic-functions -flto=auto -Wl,-z,relro 
-Wl,-z,defs -Wl,--as-needed -L/usr/lib/x86_64-linux-gnu -Llib/avilib-0.6.10

lto1: internal compiler error: compressed stream: data error
Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-9/README.Bugs> for instructions.
lto-wrapper: fatal error: g++-9 returned 1 exit status
compilation terminated.
/usr/bin/ld: error: lto-wrapper failed
collect2: error: ld returned 1 exit status
...

I tested it locally and can confirm that disabling LTO makes the package
build fine again.

I am creating this bug to document the addition of the package to the
lto-disabled-list (arch any).

As far as I have checked, there is no upstream bug reported about this
yet.
