            Bug ID: 1316206
           Summary: erl_interface: regression in erl_decode for LLONG_MIN
                    longlong value
           Product: Fedora
           Version: rawhide
         Component: erlang

Created attachment 1134565
  --> https://bugzilla.redhat.com/attachment.cgi?id=1134565&action=edit
simple reproducer

Description of problem:
In libguestfs we have erlang bindings using OTP, and one of the tests involves
passing limit values and checking that they are read as expected in the C API.

It seems erl_decode fails to decode -9223372036854775808 (which is LLONG_MIN)
as ERL_LONGLONG value, giving a ERL_INTEGER with value -1.

The attached test case contains the dump of a message (the libguestfs
add_drive_scratch call) whose second item in the tuple is a longlong.

Version-Release number of selected component (if applicable):
erlang-erl_interface-18.2.4-2.fc25.x86_64

How reproducible:
100% with the attached test case.

Steps to Reproduce:
1. build the testcase
2. run it

Actual results:
- f23:
TYPE is 137
TYPE is 17
- f24/rawhide:
TYPE is 137
TYPE is 1

17 = ERL_LONGLONG
1 = ERL_INTEGER

Expected results:
Same decoding result in f24/rawhide (i.e. as ERL_LONGLONG).

Tested the latest version, erlang-erl_interface-18.3.3-2.fc25.x86_64, from
rawhide, and indeed it works now.

Thanks!
