glibc-2.1.2-3: Expat in Mozilla won't compile with -O
Last modified: 2008-05-01 11:37:51 EDT
With glibc-2.1.2-3, expat in Mozilla chokes when trying to
compile with -O. I haven't extensively analyzed it, but it
looks like it might be a problem with a macro definition of
This is with the current Mozilla code from CVS, configured
I think my original guess that this is a memset() problem might be
wrong. If you remove the line:
#define int int32
in expat/xmltok/xmldef.h, the problem goes away. Of course this
doesn't guarantee a 32-bit integer, so it's not a real solution.
A workaround is being checked in for mozilla. However, we don't yet
know the real reason that the original code did not work, and why it
only breaks with -O.
Also, it is possible that this is an egcs problem. I'm using
egcs-1.1.2-17 from Rawhide.
I am not sure where the problem is - please reopen the bug if you can
isolate the problem further.
