GDB 5.0 does not seem to be able to set breakpoints in template functions
correctly. For example, if we compile the following program with gcc-2.95.3
#include <iostream>
template<class T>
void f(T x) {
std::cout << x << endl;
}
int main() {
f(4);
f(5.6);
}
and then step through the program until it calls f and then set a breakpoint,
the next time we run the program it does not stop at the breakpoint. Sourcing
the following script demonstrates this:
break main
run
s
break
c
disable 1
run
I am using RedHat Linux 6.0 on a Pentium II with gcc-2.95.2 and gcc-2.95.3.
The command used to compile the program was
eg++-latest -g gdbtemp.cc -o gdbtemp
(eg++-latest points to gcc-2.95.3's g++ binary. The same results
occur for gcc-2.95.2)
I do not know what compiler I used to compile gdb. It was almost certainly
gcc-2.95.2, since it was compiled on 26 Sep 2000 and that was the
release version of gcc out at the time.
The output from gdb when using the above script is:
(gdb) source gdbtemp.gdb
Breakpoint 1 at 0x804a546: file gdbtemp.cc, line 8.
Breakpoint 1, main () at gdbtemp.cc:8
8 f(4);
void f<int> (x=4) at gdbtemp.cc:4
4 std::cout << x << endl;
Breakpoint 2 at 0x805113a: file gdbtemp.cc, line 4.

Program exited normally.
