I'm trying to track down a bug in some experimental code, where an object's attribute is getting messed up. This means I'd like to examine R objects while within gdb.
One of the things I'd like to do is to examine the names of all the attributes. This is exactly what an example in the R Extensions manual section 4.11.2 "Inspecting R objects when debugging" does, but the code there doesn't work, presumably because the R internals have changed since it was written. Specifically, I get (gdb) p $a->u.listsxp.tagval->u.symsxp.pname->u.vecsxp.type.c Error: There is no member named vecsxp. where $a was set to be the attrib member of an SEXP. Could someone let me know what needs to be fixed for this to work? I imagine it's a typecast, but I haven't been able to put it together. (An example using R_PV to print the attributes of an SEXP would also be welcome, but I can probably figure that one out once I get this...)
