[Bug binutils/3146] BUG: readelf fails on ALPHA 2.16 and 2.17 due to NULL pointer

So I don't think we have some unknown reloc type that readelf should be supporting. Since the segfault has been fixed, I'm closing this bug. -- What|Removed |Added Status|ASSIGNED|RESOLVED Resolution||FIXED http://sourceware.org/bugzilla/show_bug.cgi?id=3146 --- You are receiving this mail because: --- You are on the CC list for the bug, or are watching someone who is. ___ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils
Re: [Bug binutils/3146] BUG: readelf fails on ALPHA 2.16 and 2.17 due to NULL pointer
Hi Tom, I believe that H.J.'s point is that the problem can only arise if the ALPHA-targeted binary file contains a reloc that is not known to binutils. Therefore it is in our interests to discover what this reloc is and find out whether we should be supporting it, or at least recognizing it in readelf. So, please could you supply a binary file that triggers this bug ? Then we can investigate it further. In the meantime I have applied a variant of your patch, since it is always good programming practice to check for NULL pointers before performing an indirection. This version of the patch (uploaded to the testcase) includes a second check for a NULL rtype further on in the dump_relocations function.

--- Additional Comments From tomri at gmx dot net 2006-08-31 16:44 --- Oh yes, if you remove the if .. ALPHA.. with X86, you can see the problem too. Redhat supports glibc and binutils, so only for x86? -- http://sourceware.org/bugzilla/show_bug.cgi?id=3146 --- You are receiving this mail because: --- You are on the CC list for the bug, or are watching someone who is. ___ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils

--- Additional Comments From tomri at gmx dot net 2006-08-31 17:20 --- Well, feel free to take a look at the patch. If you haven't an alpha system, than you haven't the problem. This is a BUG in the source code from readelf, not from the input to readelf. -- http://sourceware.org/bugzilla/show_bug.cgi?id=3146 --- You are receiving this mail because: --- You are on the CC list for the bug, or are watching someone who is. ___ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils

--- Additional Comments From tomri at gmx dot net 2006-08-31 17:34 --- Above the code line (see patch) there's a test for if rtype == NULL, and below this test, there´s a code sequnce using this NULL pointer. So you can test this, by setting rtype == NULL above the lines from the patch. -- http://sourceware.org/bugzilla/show_bug.cgi?id=3146 --- You are receiving this mail because: --- You are on the CC list for the bug, or are watching someone who is. ___ bug-binutils mailing list bug-binutils@gnu.org http://lists.gnu.org/mailman/listinfo/bug-binutils
