hello,

with httpd -X in console that not run.
with gdb i have this
(gdb) run -X
Starting program: /usr/local/apache2/bin/httpd -X
[New Thread 1024 (LWP 11478)]
 
Program received signal SIGSEGV, Segmentation fault.

    at sapi_apache2.c:117
117             ctx->r->status = SG(sapi_headers).http_response_code;
(gdb) quit

Can you provide a full backtrace (type 'bt' instead of 'quit')?

regards,
Derick

i've the same problem with kernel 2.4.18. useing php 4.2.0 with apache 2.0.35 i'm getting a core dump during startup of httpd. with apache 1.3.24 it works, but if i select something on a table from an oracle db i get only unreadable data trash. with php 4.1.x it's working fine....

Yes that's work with 4.1.x but not with apache 2.0.35
