Bug in multiple target debugging - invalid values in watch window #581
Description
For a while now I'm hitting a bug where values in the watch window are mixed up between targets (?) or straight up invalid when running 2 targets at the same time in the debugger. I think this is a regression because it used to work for me in the past - I'm not sure when it stopped working exactly.
I'm hitting this bug 100% of the time on a larger program - it's a bit more sporadic on a small repro but you should see it under 5 runs.
I'm running a release build (build.bat release) latest version from master - 209c5e9
Program compiled with cl c_raddbg_server_client.c /Zi
#include "stdio.h"
typedef struct State State;
struct State
{
#define PSIZE 32
int is_server;
int payload[PSIZE];
};
static State S;
int main(int argc, char **args)
{
for (int i = 1; i < argc; i++)
{
char *arg = args[i];
if (arg[0] == 's') S.is_server = 1;
else printf("Unknown argument %s\n", arg);
}
printf("Running as %s\n", S.is_server ? "server" : "client"); // edit: Fixed the printf - In the screenshot there was a bug here
if (S.is_server)
{
for (int i = 0; i < PSIZE; i++)
S.payload[i] = i * 10 + 10;
}
else
{
for (int i = 0; i < PSIZE; i++)
S.payload[i] = i * -1 - 10;
}
if (S.is_server)
{
printf("SERVER dump: ");
for (int i = 0; i < PSIZE; i++)
printf("%d; ", S.payload[i]);
printf("\n");
int break_here = 0;
break_here += 1;
}
else
{
printf("CLIENT dump: ");
for (int i = 0; i < PSIZE; i++)
printf("%d; ", S.payload[i]);
printf("\n");
int break_here = 0;
break_here += 1;
}
}
