Bug ID: 28593
Summary: DW_AT_specification is not parsed correctly.
Product: binutils
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: binutils
Assignee: unassigned at sourceware dot org
Reporter: markus.klein at sma dot de
Target Milestone: ---
Created attachment 13785
--> https://sourceware.org/bugzilla/attachment.cgi?id=13785&action=edit
ELF file for reproduction. Start objdump with the following parameters objdump
-d -S CLANG_STL_Test.elf > CLANG_STL_Test.dasm
If an ELF file with a DW_AT_specification Tag in the DWARF section is opened,
objdump is returning the error: “DWARF error: could not find variable
specification at offset xxx”
This is reproducible with code containing a structure with a static member
which is compiled with clang. Gcc does not use the DW_AT_specification in the
debug information, therefore it is not reproducible here.
I attached an ELF file for reproduction, together with the source code. Start
objdump with the following parameters
objdump -d -S CLANG_STL_Test.elf > CLANG_STL_Test.dasm
Code:
#include <stdint.h>
struct MyStruct
{
static uint32_t MyStatic;
uint32_t MyNonStatic;
};
uint32_t MyStruct::MyStatic = 12;
int main(void)
{
MyStruct myS;
myS.MyStatic++;
return 0;
}
