Description Brian Ryner 1999-08-08 00:39:20 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
memset().

This is with the current Mozilla code from CVS, configured
with --enable-optimize.

Comment 1 Brian Ryner 1999-08-08 02:19:59 EDT

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.

Comment 2 Brian Ryner 1999-08-09 16:07:59 EDT

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.

Comment 3 Cristian Gafton 1999-08-10 21:52:59 EDT

I am not sure where the problem is - please reopen the bug if you can
isolate the problem further.
