Hello,
The problem seem to be caused by the "incompleteness" of the plplot installation - it lacks the xwin driver.
On Ubuntu, for example, it's neccesarry to install the plplot9-driver-xwin package to enable plplot to work with X-windows.
Anyhow, I've changed the way GDL reacts to such situation (CVS version):
GDL> plot, sin(findgen(100))
% PLOT: plPlot installation lacks...

Thanks for reporting it.
Here's a backtrace (I've reproduced the situation with an empty startup file)
Program received signal SIGSEGV, Segmentation fault.

Hello,
I've tried the code on the current CVS version on Linux and OSX, and in both cases the result was consistent with IDL:
GDL> $echo blabla > testfile.txt
GDL> line=''
GDL> openr,gfile,'testfile.txt',/get_lun
GDL> readf, gfile, line
GDL> PRINT, EOF(gfile)
1
If possible, please provide some more details concerning your platform and GDL version.
Regards,
Sylwester.

Thanks for reporting it.
It's now fixed in the CVS version:
GDL> streg="([a-z]+://)?([^/\:?]+\.[^/\:?]+)?(:[0-9]+)?(/?[^#?]+)?(\?[^#]+)?(#.+)?"
GDL> PRINT, STREGEX("bla.vla",streg,/SUB, /EXTRA)
bla.vla bla.vla

Thanks for reporting it and for the testfile.
Quoting authors of the gzstream wrapper the is used to implement /COMPRESS keyword (http://www.cs.unc.edu/Research/compgeom/gzstream/):
... What's Missing: - Seek. The zlib library provides the necessary functionality, but we have not realized that in the wrapper (yet? ;-)...
So, that would probably be the starting point to fix it...

Hello,
In case you're compiling using gcc 4.4 this might help:
http://gnudatalanguage.cvs.sourceforge.net/viewvc/gnudatalanguage/gdl/src/antlr/CharScanner.hpp?r1=1.2&r2=1.3
(ie. try adding #include in the CharScanner.hpp file)
