[Bug binutils/4110] Broken object file crashes nm
--- Additional Comments From sliedes at cc dot hut dot fi 2007-03-25 17:13
---
Sorry for taking some time to reply. It seems I can't reproduce the SEGV
anymore myself (don't know what changed), but I do get a valgrind error. And I
also have a log of nm crashing twice on that input file. By the way now that I
test I also get the same Valgrind error with broken3.o and broken4.o. It seems
the uninitialized variable has to be still idx->shdr as probably was the case
with broken4.o, however I can't get that either to crash any more.
Here's what I get from Valgrind:

[Bug binutils/4275] New: nm does not list dynamic symbols on AIX
This repros with the nm from the AIX toolbox (version 2.14), but it also repros with a copy of nm I built as part of a cross compiler (version 2.17 from FC6 64bit to AIX 5.3.0.0). On Linux, even after a binary has been stripped, the dynamic symbols can still be retrieved. The following commands show this with hello world: [EMAIL PROTECTED] ~]$ gcc hello.c -o hello [EMAIL PROTECTED] ~]$ strip hello [EMAIL PROTECTED] ~]$ nm hello nm: hello: no symbols [EMAIL PROTECTED] ~]$ nm -D hello w __gmon_start__ U __libc_start_main U puts [EMAIL PROTECTED] ~]$ On AIX, nm does not display these symbols, even though the native dump program can still access them: [EMAIL PROTECTED] ~]$ gcc hello.c -o hello [EMAIL PROTECTED] ~]$ /opt/freeware/bin/nm hello | head 11f0 t 100069fc T .$RESTF14 10006a00 T .$RESTF15 10006a04 T .$RESTF16 10006a08 T .$RESTF17 10006a0c T .$RESTF18 10006a10 T .$RESTF19 10006a14 T .$RESTF20 10006a18 T .$RESTF21 10006a1c T .$RESTF22 [EMAIL PROTECTED] ~]$ /opt/freeware/bin/nm hello -D | head /opt/freeware/bin/nm: hello: No symbols [EMAIL PROTECTED] ~]$ strip hello [EMAIL PROTECTED] ~]$ /opt/freeware/bin/nm hello | head /opt/freeware/bin/nm: hello: no symbols [EMAIL PROTECTED] ~]$ /opt/freeware/bin/nm hello -D | head /opt/freeware/bin/nm: hello: No symbols [EMAIL PROTECTED] ~]$ dump -T hello hello: ***Loader Section*** ***Loader Symbol Table Information*** [Index] Value Scn IMEX Sclass Type IMPid Name [0] 0x2b9c 0x0002 0x00 0x050x1 0x __rtinit [1] 0xe008 0x 0x08 0x070x0 0x0001 ___memset [2] 0xf000 0x 0x08 0x070x0 0x0001 ___memmove [3] 0x 0x 0x08 0x050x0 0x0001 errno [4] 0x 0x 0x08 0x0a0x0 0x0001 malloc [5] 0x 0x 0x08 0x0a0x0 0x0001 free [6] 0x 0x 0x08 0x0a0x0 0x0001 exit [7] 0x 0x 0x08 0x0a0x0 0x0001 strlen [8] 0x 0x 0x08 0x0a0x0 0x0001 abort [9] 0x 0x 0x08 0x0a0x0 0x0001 printf [10]0x 0x 0x08 0x0a0x0 0x0001 __strtollmax [11]0x 0x 0x08 0x0a0x0 0x0001 __mod_init [12]0x 0x 0x08 0x050x0 0x0001 __crt0v [13]0x 0x 0x08 0x050x0 0x0001 __malloc_user_defined_name [14]0x2c00 0x0002 0x04 0x0a0x1 0x __start [EMAIL PROTECTED] ~]$ -- Summary: nm does not list dynamic symbols on AIX Product: binutils Version: 2.14 Status: NEW Severity: normal Priority: P2 Component: binutils AssignedTo: unassigned at sources dot redhat dot com ReportedBy: kstemen at centeris dot com CC: bug-binutils at gnu dot org GCC build triplet: powerpc-ibm-aix5.3.0.0 GCC host triplet: powerpc-ibm-aix5.3.0.0 GCC target triplet: powerpc-ibm-aix5.3.0.0 http://sourceware.org/bugzilla/show_bug.cgi?id=4275 --- 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
