This patch does not help: Even with it, test-regex still crashes in the same way: Assertion failed: err == REG_ESPACE, file ../../gllib/regexec.c, line 1077 FAIL test-regex (exit status: 134) But I found GCC binaries that I can use on this machine, and with this GCC, both the test-regex and all 'grep' tests pass! Out of the four hypotheses (a) Unportable #if code that expands to invalid code for HP-UX cc. (b) A HP-UX cc front-end bug. (c) A HP-UX cc optimization bug. (d) A HP-UX cc code generation bug. we can exclude (c) - since I had no optimization options enabled -, and (a) is unlikely as well - since it would likely have affected the compilation on HP-UX ia64 as well. Conclusion: Either (b) or (d). Bruno
