c++ - gdb pretty printer stops working if I rerun my program -


if use command run inside gdb rerun program can no longer pretty print c++ objects vectors:

$ gdb ./some_program (gdb) br some_where (gdb) run (gdb) print some_vector # vector pretty printed (gdb) run (gdb) print some_vector # vector no longer pretty printed

here's sample code used , actual gdb session:

#include <vector> #include <iostream>                                                                                                                                                                                                                       using namespace std; int main() {     vector<int> v{1};     cout << v[0] << endl; }

this this libstdc++ pretty printers bug.

you can apply this patch installed pretty printers or update whole gcc more recent version.

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
