[lttng-dev] not able to read 32-bit app traces running on a 64-bit system with relayd

[Anand Neeli]

Hi Jérémie,
Thanks for verifying this.

Is this a issue with relayd? or babeltrace?
Coz i see this only with 32-bit applications running on a 64-bit system,
along with relay of traces using relayd

Thanks,
Anand Neeli
