[That "paste" site says that the page expires in 6 days.]
Looking at the dumped data, I see three Elf32_Shdr Sections named ".rodata":
[18] .rodata PROGBITS 00093ac0 093ac0 003504 00 A 0 0 32
[28] .rodata PROGBITS 000970ac 0970ac 0002b4 01 AMS 0 0 4
[41] .rodata PROGBITS 00098a97 098a97 0001a9 01 AMS 0 0 1
while the valgrind code in coregrind/m_debuginfo/readelf.c
subroutine Bool ML_(read_elf_debug_info) ( struct _DebugInfo* di )
appears to assume that there will be only one such ".rodata":
if (0 == VG_(strcmp)(name, ".rodata")) {
if (inrx && !di->rodata_present) { \\\ only
di->rodata_present = True; /// once?
di->rodata_svma = svma;
di->rodata_avma = svma + inrx->bias;
di->rodata_size = size;
di->rodata_bias = inrx->bias;
di->rodata_debug_svma = svma;
di->rodata_debug_bias = inrx->bias;
/* NB was 'inrw' prior to r11794 */
TRACE_SYMTAB("acquiring .rodata svma = %#lx .. %#lx\n",
di->rodata_svma,
di->rodata_svma + di->rodata_size - 1);
TRACE_SYMTAB("acquiring .rodata avma = %#lx .. %#lx\n",
di->rodata_avma,
di->rodata_avma + di->rodata_size - 1);
TRACE_SYMTAB("acquiring .rodata bias = %#lx\n",
(UWord)di->rodata_bias);
} else {
BAD(".rodata");
}
}
It might be possible to confirm this diagnosis by turning on TRACE_SYMTAB
(which is controlled by command-line argument --trace-symtab=yes
and perhaps by --trace-symtab-patt=<patt> ) and looking through
what valgrind reports.
[Of course I also see the many hundreds of Sections ".rodata.<subr_name>"
and ".text.<subr_name>" and ".text.unlikely.<subr_name>" which at first
glance seem to be overkill and/or extravagant waste of space. There
should be a more-compact way to convey the information.]
