Re: [Modcplusplus-devel] Apache segfaults w/mod_cplusplus-1.4.3

[Michael S. <ms...@ca...>]

Thanks John

by looking at 'make check' I saw that the problem seems to be the 
CPPHandler that gets loaded by mod_cplusplus. mod_cplusplus loads just 
fine with the 'make check' config.

will now look into the CPPHandler issue. It has been written for 
mod_cplusplus-1.2 and confirmed to work in 1.3, but not 1.4.
