PS driver crashes when no permissions (PR#8078)
This is already fixed in 2.1.1 patched: please see the resources the
posting guide and FAQ ask you to consult _before_ sending a bug report!
o File creation errors in pdf(), postscript(), xfig() resulted
in a pointer being freed twice. (Reported by Matt McCall)
As the FAQ says
If a bug has already been reported or fixed, please do not submit
further bug reports on it.

R 2.1.1 crashes when it is trying to write a file with the postscript driver to
a directory, where the user has no permission to write. For example,
postscript("foo.ps") gives an error message: *** glibc detected *** free():
invalid pointer: 0x08a469b0 ***. The problem is at the PSDeviceDriver function
in the devPS.c file on line 2357 (free(dd);), where the same memory block is
tried to free the first time and then the second time at line 5138 (free(dev);).
I'd suggest to remove the first free function.
