R3 crashes with a segmentation fault when a binary string over 32262 bytes is loaded. The string is a compressed version of Ladislav's core-tests.r

Note: the binary string loads correctly if trace is set on.

The compressed script file is not attached yet. And you might want to use a different extension: .txt is a registered file type in more recent builds. If the problem goes away when you change the file extension, that would be really interesting to know.

The file is attached now.

The contents of the dump.txt file were dumped during debugging as the problem occurred in an Rebol.org LDS script which obtains the binary data from Rebol.org. I changed the file extension to .r anyway and the problem is the same - seg fault unless you set trace on.

While I can still reproduce this crash with A109, I can no longer reproduce it with the attached dump.txt on A110, A111 or current open source builds.
