[Octave-bug-tracker] [bug #55427] save -v7 exits with "error compressing data element"

[Markus Mützel]

Update of bug #55427 (project octave):

                 Release:                     dev => 6.2.90

Follow-up Comment #11:

The uLongf type that is used for the input and output buffer size is a
unsigned long integer. That is 64 bit on Linux, but it is 32 bit on Win64.
IIUC, the calculation that we use for estimating the destination buffer size
overflows if the source buffer is 2^32/101 bytes or larger (that is just over
40 MiB if I'm not mistaken).

I'm currently cross compiling with a changeset. If using `compressBound`
works, I'll probably push to the stable branch.
