- Recently there were posts by people who said that using gs252pm (or gsos2pm10)
- causes their swapfile to grow out of control. The fact that this happens
- when they are using gs252pm to view files with fonts leads me to suspect that
- they are not using the dll "emxlibc.dll" that I supplied with gs, but
- instead using the emxlibc.dll that came with emx 0.8e. As I pointed out
- in the file "readme.1st", in the section "***** VERY IMPORTANT****",
- the emxlibc.dll that came with emx 0.8e has a bug in the routine "frexp",
- which is used by GhostScript's font rendering routines. The bug COULD
- make GhostScript think that the fonts are HUGE, thus requiring a lot of
- memory to store or render the fonts, eventually filling the swapfile.
-
- I have tried gsos2pm10 on every PostScript file I have, including some
- that have quite a few fonts, and gsos2pm10 correctly display all of them
- except one - "warbird.ps", which was emailed to me by a user of gsos2pm10,
- Darrel Hankerson. Gsos2pm10 displays nothing for "warbird.ps", but does
- not crash or otherwise misbehave.
-
- PS: Gs252pm and gsos2pm10 do not allocate space in the swapfile directly
- or assume anything about the swapfile. The nice thing about OS/2 is that
- your program does not have to worry about managing virtual memory.
