[SR-Users] Fwd: Stack smash error when using auth_ephemeral with KEMI

[Grant Bagdasarian]

Hi Daniel,

FYI, the following also ends up in the stack smash error:
_.x.modf("autheph_authenticate", "1576734089:grant", "1234")

I also tried with the devel nightly deb package, which also resulted
in the same error.
I'm unsure if this error also happens when using the native Kamailio
script, as my routing logic is built using the Python3 module.
Will give the native script a try soon, and report back.

Regards,

Grant
