Re: Apache::ASP: crash when placed in startup.pl
Doh! I forgot to say what I'm running: Apache::ASP v. 0.17 SDMB_File v. 1.0 mod_perl v. 1.21 Apache v. 1.39 RedHat 6.1 on Linux 2.2.12 x86 At 11:30 AM 1/14/00 , you wrote: Hi, I'm trying to preload and precompile all ASP scripts by including Apache::ASP in the startup.pl. However, when I do so, httpd core dumps with a segmentation fault in SDBM_File: Program received signal SIGSEGV, Segmentation fault. 0x403dfe27 in boot_SDBM_File () from /usr/lib/perl5/5.00503/i386-linux/auto/SDBM_File/SDBM_File.so (gdb) Quite frankly, I have no idea where to go from here. Any suggestions? Thanks Dmitry Beransky

Re: Apache::ASP: crash when placed in startup.pl
Yep, everything runs just fine if I don't preload Apache::ASP. My apache/mod_perl are rebuilt, but I'm still using Perl off the original RedHat distribution (totally forgot about his). I can try recompiling it...I'll be back with the result shortly.

I don't know about this, are you sure you copied over your new modperl httpd to /usr/local/apache after the build, and did a full stop / start, this is a common step overlooked by the best of us. Beyond this, I think it would be a shame if you couldn't preload Apache::ASP because of SDBM_File, you might want to research the archives a bit on other preload problems people have had, as they are likely related. I do my UNIX work on Solaris and have not ever dealt with this problem personally, so can't really pursue it for you.

Yes, I'm using the new build. I've compiled perl with debugging turned on
and now gdb shows exactly where the problem occurs: line 267 of SDBM_File.c
262 #ifdef __cplusplus
263 extern "C"
264 #endif
265 XS(boot_SDBM_File)
266 {
267 dXSARGS;
268 char* file = __FILE__;
269
270 XS_VERSION_BOOTCHECK ;
I guess at this point I got to go to a bookstore, get a book on GDB and get
my hands dirty with some debugging :).
Thanks

Re: Apache::ASP: crash when placed in startup.pl
This sounds like the same corruption problem that I talked about in my
last message - could you try exporting LD_PRELOAD=/path/to/modperl.so?
(I'm guessing from context that you're using a DSO - apologies for the
non-sequitor if I'm wrong, I just got back on the list).
