Dear all,
When using gdb to debug my C code, I use R_PV to show the content of
SEXP variables:
SEXP sexp; // it is a data.frame
SEXP colNames = getAttrib(sexp, R_NameSymbol);
A strange thing is that after halting the program:
(gdb) p R_PV(colNames)
does not show the content of colNames. I am positive my code is right
because if I insert "PrintValue(colNames);" in the c code, it will
print the right value. My debug result shows that the variable
"colNames" failed the "isObject" call. I am not sure whether this is a
new feature or bug. Anyone can help?
Thanks,
Gang Liang
