debugging - C++: Do I need GCC and GDB with the same version to debug -

-

i developing in c++ on windows mingw. have debugging problems @ moment.

i must use , old version of gcc (4.4). wondering if possible compile old gcc , debug new gdb?

what link between 2 of them?

thanks!

(any pointers regarding debugger crashes appreciated too! know need sure use debug dlls)

gdb , gcc separate programs -- separate source bases (with bit of shared code, though not much), separate maintainers, different release schedules, , different version numbers. share bit of culture , of course there coordination.

gdb reasonably backward compatibility. keeps workarounds bugs in debuginfo emitted older versions of gcc , other compilers. means can upgrade gdb while keeping same gcc version.

the reverse, though, not case. new version of gcc emits debug info older gdb cannot understand. in situation must upgrade gdb well. in limited situations can pass compatibility flag gcc ask downgraded debug info, isn't possible. and, since simple upgrade gdb, might well.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
