Subject: [Rd] Open device -> glibc 2.3.4 bug for Redhat Enterprise 4?
Message-ID: <17080.17973.699405.241927@stat.math.ethz.ch>

We have been using Redhat Enterprise 4, on some of our Linux
clients for a while,
and Christoph has just found that opening an R device for a file
without write permission gives a bad glibc error and subsequent
seg.fault:

> postscript("/blabla.ps")
*** glibc detected *** double free or corruption (!prev): 0x0000000001505f10 ***

or

> xfig("/blabla.fig")
*** glibc detected *** double free or corruption (!prev): 0x0000000001505f10 ***

and similar for pdf();
does not happen for jpeg() {which runs via x11},
nor e.g. for 

> sink("/bla.txt")

-------

Happens both on 32-bit (Pentium) and 64-bit (AMD Athlon)
machines with the following libc :

32-bit:
  -rwxr-xr-x  1 root root 1451681 May 13 00:17 /lib/tls/libc-2.3.4.so*
64-bit:
  -rwxr-xr-x  1 root root 1490956 May 12 23:26 /lib64/tls/libc-2.3.4.so*

-------

Can anyone reproduce this problem?

Regards,
Martin
