[Haskell-cafe] tplot (out of memory)

[Malcolm Wallace]

For the record, it turned out that the key difference between the linux machines was the fonts packages installed via RPM.  The strace utility told me that the crash happened shortly after cairo/pango attempted (and failed) to open some font configuration files.  After installing some of the X11 font packages (and some others too), the crash went away.

> Did you ever solve this?  I have a similar message ( user error (out of memory) ) arising from a different app (not tplot) that uses the Haskell Chart library (and cairo underneath).  On some linux machines, it crashes, on others it works fine.  I can find no environment differences between the machines.  The app does not use a lot of memory, and the machine is not running out of physical or swap.
