Under mod_perl 1.25 I get segfaults related to config directives. I tracked this down to perl_config.c, perl_perl_create_cfg, where the values of PERL_DIR_CREATE (or PERL_SERVER_CREATE) had been overwritten or something (gdb said "Out of bounds" for the type variable). In AxKit.xs (generated by Apache::ExtUtils) I had: BOOT: XS_AxKit.name = "AxKit"; add_module(&XS_AxKit); stash_mod_pointer("AxKit", &XS_AxKit); register_cleanup(perl_get_startup_pool(), (void *)1, remove_module_cleanup, null_cleanup); If I commented out the last two lines there (because they were the only difference I could see from older mod_perls), the segfaults went away. For those wondering, this has been the cause of Take23 (and AxKit.com|org) outages this weekend.
