Sorry for the bad title. I couldn't come up with anything better.
'make check' fails both on the natty buildbot and on my machine with Fedora 15 32 bits, with failures in Matrix.swf.
This is from the natty buildbot but mine on Fedora 15 is exactly similar.

Me and strk played around with the testcase and compared with Adobe's plugin. By getting some more decimals we found that they begin to differ a bit after 13 decimal places.
For comparason:
adobe: -0.444108975682838 gnash: -0.444108975682852
Because this is present in Natty and Fedora 15 but not in the other build bots such as squeeze it might be some of the tool changes, for instance a new gcc.
I have tried to compile gnash with -O0 and found no difference.
