Hi,
gdb-7.2 seems to have some trouble with c++ symbol completion for setting break
points
which did not show up in gdb-7.1 and earlier (built myself with gcc-4.3.2 on
opensuse 11.1 64bit):
a) for the small hello-world program below, when I try to set a bp to "h1" by
typing
b 'h1<TAB>
sometimes gdb immediately completes to 'h1()' -- no other signatures are shown.
this happend several times (new gdb processes) when testing this bug sample,
but right now it's correctly working again as expected:
(gdb) b 'h1<TAB>
h1 h1() h1(char*) h1(int)
(gdb) b 'h1
-------------------------------------------------------------------------------
#include <iostream>
void h1()
{
std::cout << "Hello\n";
}
void h1(int i)
{
std::cout << "Hello " << i << "\n";
}
void h1(char *s)
{
std::cout << "Hello " << s << "\n";
}
int main()
{
h1();
h1(1);
h1("2");
}
-------------------------------------------------------------------------------
b) from a colleague who first pointed at the gdb07.2 problems using the
attached "gdb.bug-cpp":
"Junk at end of arguments"
Using gcc-4.4.3
> gdb ./gdb-bug

First try:
use autocompletion, which gives an extra space after closing hyphen.
Second try:
use history and remove extra space.
