I am getting repeatedly in Rivet: [core:notice] [pid 13958] AH00052:
child pid NNNN exit signal Segmentation fault (11)
Hello. I am having a serious issue. This is the log:
[Sat Dec 15 02:09:28.054892 2018] [mpm_prefork:notice] [pid 13958] AH00163:

pid 13966 exit signal Segmentation fault (11)
After debugging my website code and trying to find where the problem is, I
found that tdbc::mysql package makes Rivet crash.
My website depends heavily on tdbc::mysql.
This is my website Rivet information like php_info() page.
http://superlinux.net/info.rvt
I made the website as a little demo on the potentials of Rivet and how
would anyone make use of Tcl instead of PHP.
Please try this simple code in an rvt file just reproduce the issue:
<?
#This line works just fine
puts [package require Rivet]
#This line makes the whole page crash with a segmentation fault.
puts [package require tdbc::mysql]
?>
Thanks.

Maybe you are on an OS that uses mariadb (like fedora), or a newer
version of mysql than the ones tdbc supports?
tdbc::mysql is buggy, if it cannot find the client library it will cause
a segmentation fault (which is totally unacceptable for something
shipping with tcl core...).
If this is the case, you are out of luck.
I have submitted many tickets, but I don't know who is responsible for
fixing this. These bugs are open for 2+ years now.
I.e.:
http://core.tcl.tk/tdbcmysql/tktview?name=040c635cb3
http://core.tcl.tk/tdbcmysql/tktview?name=44cc436b4e
http://core.tcl.tk/tdbcmysql/tktview?name=e449b3ccb5
If you run plain tclsh from command prompt (the same one used by rivet),
can you do "package require tdbc::mysql"?
Is it working? If tclsh segfaults, then the problem is not in rivet...

Sorry for the stupid question, the version was in the info. I have to
reformulate it since I read it's version 3.2, which is the version
number I gave to the development in trunk. Are you running a module
built from the latest commit available?
My preliminary tests on 3 different installations worked just fine (I
tweaked the script in order to have better reading)
<?
#This line works just fine
puts [::rivet::xml "Rivet: -> [package require Rivet]" pre]
#This line makes the whole page crash with a segmentation fault.
puts [::rivet::xml "tdbc::mysql -> [package require tdbc::mysql]" pre]
?>
------
Rivet: -> 3.1
tdbc::mysql -> 1.1.0
Rivet: -> 3.2
tdbc::mysql -> 1.0.6
Rivet: -> 2.3
tdbc::mysql -> 1.0.6
