I am affraid it's the best I can do, it's very hard to compile debug on win32 I have seemingly compiled perl58 DEBUG (there was a complain about missing vc60.pdb, and I supplied one I found ) I cannot compile debug either modperl1-99_04 either _05 against my debug perl. so I just copied from perl/site/lib everything concerning modperl into the perldebug site/lib tree (don't know if this is liable) I also properly installed DBI-1.30 in the perldebug site/lib tree then I ran apache in windbg and got this stacktrace also here is the last loading modules sequence inside apache ModLoad: 6fbf0000 6fbf6000 C:\Apache2\modules\mod_userdir.so ModLoad: 28000000 281a3000 C:\perld\bin\perl58.dll ModLoad: 10000000 10010000 C:\Apache2\modules\mod_perl.so ModLoad: 71a90000 71a98000 C:\WINDOWS\System32\wshtcpip.dll ModLoad: 00360000 00383000 C:\perld\site\lib\auto\DBI\DBI.dll ModLoad: 00390000 00399000 C:\perld\site\lib\auto\Apache\RequestRec\RequestRec.dll ModLoad: 003a0000 003a6000 C:\perld\site\lib\auto\Apache\RequestIO\RequestIO.dll ModLoad: 003b0000 003b8000 C:\perld\site\lib\auto\ModPerl\Const\Const.dll ModLoad: 003c0000 003c5000 C:\perld\site\lib\auto\Apache\Const\Const.dll -->error at this point since it is past DBI.dll , maybe this is because I copied incompatible modperl to perld site/lib tree. hope this can help pascal
