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. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?55427> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
