I have problems accessing a rather long file after enabling --trans-sid. Apache-childs die after processing X lines of that file. (I tested to add one more char at the end of the last processed character, but it was not displayed)

Is it possible that the buffer --trans-sid uses to store the page (and process it) in is too small?

I have no gdb installed yet, or can create a logfile, so perhaps this could be approved by someone else... 

I will try to reproduce it on another system and get a trace from that...

I configured it on the original system with:
./configure  --with-apxs=/usr/local/apache/current/bin/apxs --enable-versioning --with-mysql --enable-track-vars --enable-syvshm --enable-sysvsem --with-config-file-path=/etc --enable-url-includes --enable-trans-sid

On a second system I used:

./configure  --prefix=/usr --libexecdir=/usr/libexec/php --sysconfdir=/etc/ --sharedstatedir=/var/state/php --localstatedir=/var/state/php --with-apxs --enable-versioning --enable-inline-optimization --enable-calendar --with-gdbm --enable-ftp --with-gettext --with-mysql=/usr --enable-trans-sid --enable-sysvsem --enable-sysvshm --with-zlib --with-config-file-path=/etc/php.ini

I can't get a logfile, so I used:
gdb /usr/local/apache/current/bin/httpd
(gdb) run -X 

and got (before accessing the page)

Starting program: /usr/local/apache/current/bin/httpd -X
warning: find_solib: Can't read pathname for load map: Input/output error

Error while mapping shared library sections:
"/sbin/": not in executable format: Is a directory.
Error while reading shared library symbols:
"/sbin/": can't read symbols: Is a directory.
Cannot access memory at address 0xc3815b00.
(gdb)

But I think that is a gdb-problem...

Okay - we've tried nearly everything to get arout this "bug", until we found a small error in the html-code of the crashing page.

It looks like trans-sid does not like broken pages - it gets confused if a ">" is too much, or a " is not closed, I think.

But as this has nothing to do with filesize and trans-sid I close this report.
