Hi, To investigate further my issue, I ran all iostream unit tests on Android, and found 5 tests to fail (even though there seem to be a duplicate). Other tests, including "gzip_test", are okay. Results follow. I'm willing to help & debug, but I have now clue about where to start from. Anyone has one (clue, of course)? Thanks.

I know Android is not actively maintained, but I need multichar filters (gzip_compressor & gzip_decompressor are multichar and thus fail). And I wonder why this test fails. I could not run the regression test on iOS, but my original code (using gzip_decompressor) works as expected under iOS, and Windows, and MacOSX. I have no clue about how to solve the issue. Any idea? Thank you. Cheers, Sukender
