DSO installation weirdness Apache 2.0.x and Solaris 8 32 bits

Hello, hope there is someone can help me with this... Env: apache 2.0.48 php 4.3.3 Sun C 32 bits compilation Compilation does not show any error however once the module is loaded into apache the server core dumps.. now the weird things is that if I compile all the above in 64 bits it works just fine! also with apache 1.3.29 in both 32bits and 64bits it works just fine so not sure whatever this is a bug in php or apache but its works in 64bits.. it just does not make sence... ill try with older php version today but meanwhile anyone seen this before? thanks -ls
