The problem only happens on our systems with two nocona 64 bit CPUs

Configure Command =>  './configure' '--with-_lib=lib64' '--enable-sockets' '--enable-pcntl' '--enable-sigchild' '--with-bz2' '--enable-discard-path' '--with-mysql=/usr/local/mysql' '--with-curl=/usr/local' '--with-dbase' '--disable-short-tags' '--enable-track-vars' '--without-gd' '--enable-sysvshm' '--enable-sysvsem' '--disable-debug' '--enable-magic-quotes' '--enable-memory-limit' '--with-config-file-path=/usr/local/lib' '--with-zlib'

Try again. I broke the build with bad commit. (I fixed it just a few minutes ago though :)
 [2005-03-17 12:40 UTC] ian_real at dominios dot net 
It works now, thanks!

Just the snapshot version seems to have even more bugs...

Bug #22544 (TrueColor transparency in PNG images). [ext/gd/tests/bug22544.phpt]
Bug #24155 (gdImageRotate270 rotation problem). [ext/gd/tests/bug24155.phpt]
gdimagefill() function (Bug #19366 (fixed in bundled libgd)) [ext/gd/tests/bug27582_1.phpt]
Bug #31213 (Sideeffects caused by bug #29493) [ext/standard/tests/array/bug31213.phpt]
xslt_set_object function [ext/xslt/tests/xslt_set_object.phpt]

Any idea when 4.3.11 will be released?

Hello,

Please do not mix topics :)

If you find other bugs not related to this one, open new ones. Thanks.

For the record, about gd tests, it seems that the md5 signatures of result images differ but the tests work.

can you tell me which part of the code you changed, so I can patch it on 4.3.10?

Thanks

This bug is fixed. As for patches, either have a look in CVS or get a snapshot (recommended!)
