Description Joe Orton 2002-04-23 13:15:54 UTC

Description of Problem:
On one HP-UX 11.00 machine, AxKit 1.5.1 segfaults when serving the example pages.

Version-Release number of selected component (if applicable):
axkit-1.5.1

How Reproducible:
Only reproducible after upgrading to axkit-1.5.1, perl-xml-modules-5.6.1-1,
perl-Apache-Request-1.0-1.

Steps to Reproduce:
1. install 4.0 beta
2. upgrade libxml, libxslt to 2.4.18-1, 1.0.14-1
3. upgrade to perl-xml-mods 5.6.1, axkit 1.5.1, perl-Apache-Request-1.0-1

Comment 1 Joe Orton 2002-04-24 12:59:42 UTC

The backtrace leads to Zlib.sl (Compress::ZLib) in perl-xml-modules; the
segfault is not reproducible when either:

- adding "AxNoCache On" to conf/axkit.conf
- using the Zlib.sl from the perl-xml-modules-5.6.0-7 (from the beta release)
- rebuilding Zlib.sl against zlib-1.1.3

The other difference between the beta release and HEAD is that -O2 is used in
HEAD.  This is suspected to be a compiler optimisation bug; currently
investigating use of a newer gcc release.

Comment 2 Joe Orton 2002-04-24 19:49:25 UTC

After upgrading from gcc 2.95.2 to 3.0.4, and rebuilding rpm-utils (zlib),
libxml, libxslt, and perl-xml-modules, this problem is no longer reproducible.
