ASF GitHub Bot commented on THRIFT-3831:
----------------------------------------
GitHub user jmesmon opened a pull request:
https://github.com/apache/thrift/pull/1085
THRIFT-3831 in test/cpp explicitly use `signed char`
`char`'s signed-ness is implimentation dependent, and in the case where
`char` was not signed, we previously recieved errors like
thrift/0.9.3-r0/git/test/cpp/src/TestClient.cpp:404:15: error:
narrowing conversion of '-127' from 'int' to 'char' inside { } [-Wnarrowing]
(This example from gcc-6 on arm)

> Specifically, we get a bunch of errors like:
> test/cpp/src/TestClient.cpp:404:15: error: narrowing conversion
> of '-1' from 'int' to 'char' inside { } [-Wnarrowing]
> gcc faq talks about this: https://gcc.gnu.org/wiki/FAQ#Wnarrowing
> I've only seen this in gcc-6, but the faq seems to indicate it could occur in
> gcc-5 as well.
