This bug system is for bugs in core PHP. The ssh2 extension is a PECL project so reporting of this bug probably should have started with http://pecl.php.net/bugs/ Of course, beyond that the actual problem is in libssh2 which is a sourceforge.net project so it *really* belongs in that bug system. Sorry it's so convoluted, but there are a fair number of cooks in the kitchen. I will continue to work on the libssh2 bug despite closing this report.
