And do NOT use --enable-maintainer-zts !!!
 [2005-11-15 17:46 UTC] grover at us dot ibm dot com
Obtained latest php5 and libxml2. 
Removed --enable-maintainer-zts.
Now having problems in compiling parse_date:
YYCTYPE yych;
#define YYCURSOR cursor;
#define YYMAKER s->ptr;

yych = *(YYMARKER = *++YYCURSOR);  << this gernerated too many errors. Compile complains about mismatch between assignment of char and char* types.  I overcame the problem by going back to parse_date.c.orig. Continueing compile.
 [2005-11-17 15:58 UTC] grover at us dot ibm dot com
After going to the latest php5, the crash is gone, but almost none of the apps worl correctly. I get constant error about reformatting pages and many are either displayed with junk at the begining OR not at all.

I have changed my compile options a little and seem to be getting a core dump that looks very similar to bug 28064. Can I shift to using the zend engine in the lastest php5 with 5.0.4? Or should I expect that to also be problematic?

Thanks!

If you have any compile problems, please REPORT them here.
If you have any other problems, you need to tell us about them. Just saying "it does not work" doesn't help much..
