I was able to print the addess of any symbol or do a "ptype" on any
symbol using gdb 6.4 with the generated
Now I compile the very same code using gcc 3.4.6 using the -g option
again. Here, I get an error saying
"There is no field/member named <symbol name>".
This very symbol was found when the code was compiled using gcc 3.2.2.
First, please don't cross-post to both gcc and gcc-help mailing lists.
This belongs on gcc-help; future replies should only go to gcc-help.
You can see if there is debugging information in the object file

want to check both the object file and the executable. If the symbol
appears to be defined correctly, then the problem may be in gdb.
