Hello,
I'm trying to run a simple test using the tcp_echo application using
19.08.1-release, but it just crashes pretty early on. I built a debug version
and tried to debug the crash that happens in mspace_malloc:
void* mspace_malloc(mspace msp, size_t bytes) {
mstate ms = (mstate)msp;
if (!ok_magic(ms)) {
USAGE_ERROR_ACTION(ms,ms);
return 0;
}
The call to ok_magic returns 0 and the program exits. Stepping through the
code, the issue happens while still trying to connect to VPP at initialization:

The internal test echo client/server work fine, so I think I've set things up
correctly but I'm not sure if I'm missing something for the external
client/server, or if they work for everyone else on 19.08.1-release.
All I do is bring up VPP, set an IP address on the interface, and then run the
tcp_echo application. Can someone please let me know if the tcp_echo
application works for them on 19.08.1-release, and if so are there any other
steps needed for it to run other than what I've mentioned?
Thank you in advance!
Dom
