[Valgrind-users] feature upgrade

[Bob R. <bo...@br...>]

Hi,

When valgrind alerts the user of a 'Conditional jump or move depends on
uninitialised value(s)' is there any way it could tell you either
   - The name of the variable that is causing this to happen
   - The address of the data that is causing this to happen

Here is an example, I am making up the function names, source file and
line numbers. The best granularity I get in this example is the source
file and line number.

==16717== Conditional jump or move depends on uninitialised value(s)
==16717==    at 0x8D32303: func1 (foo.c:100)
==16717==    by 0x8D3B7A2: func2 (foo.c:101)
==16717==    by 0x8165B2A: func3 (foo.c:102)
==16717==    by 0x8166C81: func4 (foo.c:103) 

Could I get the symbol name causing the problem? What about the address
of the variable causing the problem?

The reason I ask is because the if statement on the line where valgrind
found the error is really complicated and it's difficult for me to
determine what symbol is causing the problem. The symbol name would be
most helpful, but if that could not be found, the address name would be
also. At least, it would be helpful when using the 'db-attach' feature.

I could look into adding this feature if it's simple, and if I could be
put in the correct direction.

Thanks,
