Nondeterministic T5559 failures on CI
T5559 test case occasionally fails on CI, forcing me to restart builds to get a green build status. Here is one example from a
"gs" -dNODISPLAY -dBATCH -dQUIET -dNOPAUSE "profiling/should_run/T5559.run/T5559.ps" hp2ps output for T5559is not valid PostScript *** unexpected failure for T5559(profasm) <elided> SUMMARY for test run started at Thu Feb 21 00:32:08 2019 UTC 0:44:16 spent to go through 6839 total tests, which gave rise to 26523 test cases, of which 19210 were skipped 42 had missing libraries 7178 expected passes 92 expected failures 0 caused framework failures 0 caused framework warnings 0 unexpected passes 1 unexpected failures 0 unexpected stat failures Unexpected failures: profiling/should_run/T5559.run T5559 [bad heap profile] (profasm)
Aside from the nondeterministic test failure, this also reveals a minor bug: it prints
T5559is not valid PostScript, which should probably be
T5559 is not valid PostScript instead.
