Yes, I have if I use C locales:

$ LC_ALL=C ./src/bison -fcaret /tmp/foo.y 2>&1 | xxd
00000000: 2f74 6d70 2f66 6f6f 2e79 3a31 2e31 3a20  /tmp/foo.y:1.1: 
00000010: 6572 726f 723a 2069 6e76 616c 6964 2063  error: invalid c
00000020: 6861 7261 6374 6572 3a20 275c 3027 0a20  haracter: '\0'. 
00000030: 2020 2031 207c 2000 0a20 2020 2020 207c     1 | ..      |
00000040: 205e 0a                                   ^.

And it is slightly different to what I get if I use (my default) 
en_US.UTF-8:

$ ./src/bison -fcaret /tmp/foo.y 2>&1 | xxd
00000000: 2f74 6d70 2f66 6f6f 2e79 3a31 2e31 3a20  /tmp/foo.y:1.1: 
00000010: 6572 726f 723a 2069 6e76 616c 6964 2063  error: invalid c
00000020: 6861 7261 6374 6572 3a20 e280 985c 30e2  haracter: ...\0.
00000030: 8099 0a20 2020 2031 207c 2000 0a20 2020  ...    1 | ..   
00000040: 2020 207c 205e 0a                           | ^.

But it still fails even if I use:

$ /usr/bin/env LC_ALL=C /usr/gnu/bin/make check

Any hint, please?

Thank you
