>Description:
The attached example triggers a bug in gcc making it dump the type info name as an undefined symbol into the resulting object file.


In the example the class X shall be compiled and 


the type info and type info name should be in the object-file X.o. 


Gcc fails to create the type info name, however.


After some tests two workarounds could be found:


* comment the "pragma interface" line in Y.h


* comment the member using "vector" of class Y





The attached example also includes the .ii-file which is said to be useful to you...





a complete output of gcc -v reads as follows:





Reading specs from /opt/gcc/3.2/usr/local/bin/../lib/gcc-lib/hppa2.0n-hp-hpux11.00/3.2/specs


Thread model: posix


gcc version 3.2





>How-To-Repeat:
-extract the tarball


-use build.sh to generate X.o andto  check the type info symbols


-I figured that HP-UX-gcc's have problems with type info


 but this is the first test case I could minimize to that level
