see also: bug on xfig A RH 6.0 alpha system PC 164 LX w Matrox Millenium II with all updates till today. After upgrading to ghostscript-5.10 it doesnt display any gray colored areas in documents. A remote running ghostscript from a RH 6.0 ix86 system (without the XFree updates) does work ok, so I assume its not directly an X problem. I am unsure if the problem started after the update to RH 6.0 from 5.2 or after installing the recent X updates. reverting to ghostscript-4.10 from RH 5.2 fixes the problem.
I just tried with gs 5.50, same problems. No grays rendered. Also gs lower than 5.5 produces erroneous pdfs out of eps for me, specifically is cannot render squares with one line missing, it always renders them with all 4 lines. Test file on request. 5.50 can convert these correctly under x86 and alpha. Under alpha the grays problem remains.
can you please attach a test .ps file? Send it as an e-mail and it will be attached. We can't use GS 5.50, the license forbids it. We may only use the GPLed 5.10 version for now.
Confirmed. ghostscript built with gcc-2.95.1 does not display this behavior, so it's apparently a compiler bug.
In the meantime, ghostscript-5.10-10, which will be in the next Raw Hide release, should work.
Do you know anything about what code in ghostscript is causing the problem? Without further investigation, it is hard to know whether the compiler is indeed buggy or whether this is caused by some of the non-comformant code in ghostscript (which I know there is some of - e.g. see comments in gs5.10-rth.patch although that particular case is presumably worked around). I don't know if there is a "policy" about what part of the diagnosis you should do, Bill, and what I should do, but the first step is to find the part of ghostscript which is being compiled wrong. Of course the workaround in -10, of turning off optimization, might be best for the short run.
The problem not fixed in -10 is presumably unrelated to a compiler bug. The problem fixed in -10 may be a compiler bug (or may not) but we would need more information to say (for example, does -O2 -fno-strict-aliasing fix it like omitting -O2 does?). (in response to the following email, duly archived): Checked ghostscript-5.10-10 from rawhide: fixes the "cannot render gray" problem. Does NOT fix the "incorrectly translates a drawn bracket to a rectangle when translating ps -> pdf" problem.
grays problem fixed for next release, we aren't sure of the pd --> pdf issue.
