From Bugzilla Helper: User-Agent: Mozilla/4.78 [en] (X11; U; Linux 2.2.19 i586) Description of problem: lpq crashes with a segmentation fault when trying to query entries in a printer queue when there are entries in it. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Print something (e.g. RHS Printtool -> Tests -> Print Postscript test page) with printer switched off. (This will make sure the queue can't empty.) 2. At a shell: lpq -Plpc Actual Results: Segmentation fault. (no other information given) Expected Results: An entry detailing the entry in the queue, who sent it and how big it is. Additional info: Occured both with the RHLinux compiled binary package, and a package recompiled locally from the source RPM. This is with lpr-0.50.1-1
My printer configuration: Epson Stylus Color 880, connected via parallel port. Using Epson Stylus Color (UP) driver on /dev/lp0, with rhs-printfilters-1.63-4.rh6.2.i386.rpm installed.
I get the same behavior (segfault) for a remote lpd printer. Going back from package lpr-0.50.1-1 to lpr-0.50-7.6.x fixed the problem. ftp://updates.redhat.com/6.2/en/os/i386/lpr-0.50-7.6.x.i386.rpm
This line has been lost from previous lpr-0.50 version. This makes sense, when cp here previously has a NULL value taken from the (cp = checkremote()) assignment fews lines above. --- lpr-0.50.1/common_source/displayq.c.bak Tue Nov 6 10:40:59 2001 +++ lpr-0.50.1/common_source/displayq.c Tue Nov 6 10:41:15 2001 @@ -159,6 +159,7 @@ warn(); else { /* get daemon pid */ + cp = current; ep = cp + sizeof(current) - 1; while ((c = getc(fp)) != EOF && c != '\n' && cp < ep) cp++;
Grumble. Will fix (again).
This is fixed now.
