leack-check=full is really not needed here as we didn't want the leak
reports, just the invalid memory accesses reported by valgrind/memcheck.

Anyway, valgrind didn't say anything useful. Still the "stack smashing
detected" error is telling us we're writing out of bounds of an array or
something.

Looking at the MMQcdmSerialPort response parser, there is something that
we're not doing very well (playing with GByteArray internals). I tried
to prepare a fix for that in the 'aleksander/fix-qcdm-parser' branch in
MM git, and wouldn't mind a review and more tests with it before merging
to git master... Whether that is the fix you need, I don't know yet :)
