First of all, please try to the latest version of tcltklib on CVS. 
If you use Ruby 1.8 or 1.9, I think that you'll be able to 
replace only tcltklib.c (and stubs.c) to the latest version(s). 

If you get SEGV on the latest also, please report the followings.
---------------------------------------------------------
 * Ruby version: 
     return value of "ruby -v"

 * Compile information of tcltklib
     return value of "ruby -r tcltklib -e 'p TclTkLib::COMPILE_INFO"

 * Tcl/Tk library version: 
     return value of "ruby -r tk -e 'p Tk::TK_PATCHLEVEL"

 * pthread support on Ruby: 
     For example on linux, does "ldd /usr/local/bin/ruby" include
     libpthread.so ?

 * thread support on Tcl/Tk libraries: 
     For example on linux, does "ldd /usr/local/lib/libtcl8.4.so" 
     include libpthread.so ?

 * release date of tcltklib: 
     return value of "ruby -r tcltklib -e 'p TclTkLib::RELEASE_DATE'

 * release date of tkutil: 
     return value of "ruby -r tkutil -e 'p TkUtil::RELEASE_DATE'

 * release date of tk: 
     return value of "ruby -r tkutil -e 'p Tk::RELEASE_DATE'

 * (If you can) the script which raises SEGV

 * (If you can) the patch to fix the SEGV trouble ;-)
---------------------------------------------------------

If you use some Tcl/Tk extensions, please check whether the extensions
are compiled under current Tcl/Tk libraries. 
The reason of SEGV sometimes depends on the extensions. 
If so, that cannot be fixed on Ruby/Tk side probably.
Please try the latest version of such extensions.
