This is my first bug report to GCC, I hope it's OK.

I understand that zip files are not liked here, but the file is too large to attach uncompressed.

Alternatively, I have uploaded the same file (in uncompressed form) to mediafire.com: http://www.mediafire.com/file/wnu5mwksq926jra/JSGlobalData.ii

Sorry for the inconvenience.
Comment 2 Richard Biener 2010-09-27 11:07:26 UTC 
This has been fixed and there is a duplicate bug about this.  I just can't
find it because bugzilla is slow these days.
Comment 3 Richard Biener 2010-09-27 11:08:35 UTC 
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45580 it was.
