I've run into a few failures with 'make test' after building ccache and I'm hoping someone here has insight into what might be causing them, or can provide some leads on how to investigate further.
ccache versions: 3.3.6 and 3.4.1 build process: straightforward: ./autogen.sh; ./configure; make; make test Platforms and compilers: I'm tied to some fairly outdated platforms and compilers: the primary targets are Suse Linux Enterprise Server, v11 (service packs 2 and 3) and v12 (service packs 1 and 3). I'm using the stock compiler packages for those systems, which are gcc-4.3.4 for SLES11 and gcc-4.8.5 for SLES12. However, I've also reproduced the same results on a SLES12 system with spack and several more recent variants of gcc: 5.5.0, 6.4.0, 7.2.0. Test failures: output below the .sig; note that I've jerry-rigged the test script by commenting out the "exit 1" in the test_failed function so that it would try them all; subsequent failures for the same test suite are likely just reflections of the first failure for each. 10 tests fail in total; the rest seem to be fine, and the same tests fail with the same unexpected values for all of the platform/compiler combinations I have tried. Please let me know what other information might be useful. Thanks!
