Status update:
For some (yet) unknown reason all libgo tests fails with a segfault when
run in the build tree: make, sh or something else, the test commands are
rather hard to track.
However, running the tests manually, sigh!, after installing gccgo and
libgo5 from gcc-4.9-4.9.0-1 with split stack support the result is as
follows:
Total: 122
PASS: 95
FAIL: 27
Number of tests succeeding with libpthread's stack guard fixed: 33 (and
the other libc fixes)
Note: In many of the failing tests, only a small subset of each test
fails.
GNU/Hurd should now to be considered for upstream inclusion?
Updated patches will be sent again to gcc-patches for review.
