If I set breakpoints in the overloaded constructors (AZA::AZA) and similar
overloaded methods (AZA::BZB) I get:
(gdb) inf break
Num Type Disp Enb Address What
1 breakpoint keep y 0x08048890 in AZA at overgdb.cc:12
2 breakpoint keep y 0x080488c8 in AZA at overgdb.cc:17
3 breakpoint keep y 0x080488f4 in AZA::BZB(int) at overgdb.cc:22
4 breakpoint keep y 0x0804892c in AZA::BZB(double) at overgdb.cc:27
which presumably should be:
(gdb) inf break
Num Type Disp Enb Address What
1 breakpoint keep y 0x08048890 in AZA::AZA at overgdb.cc:12
2 breakpoint keep y 0x080488c8 in AZA::AZA at overgdb.cc:17
3 breakpoint keep y 0x080488f4 in AZA::BZB(int) at overgdb.cc:22
4 breakpoint keep y 0x0804892c in AZA::BZB(double) at overgdb.cc:27
So I wonder if GDB is reading the symbol information correctly.
readelf gives me:
<2><5d00>: Abbrev Number: 53 (DW_TAG_subprogram)
DW_AT_sibling : <5d19>
DW_AT_external : 1
DW_AT_name : AZA
DW_AT_decl_file : 1
DW_AT_decl_line : 15
DW_AT_declaration : 1
<2><5d19>: Abbrev Number: 54 (DW_TAG_subprogram)
DW_AT_sibling : <5d40>
DW_AT_external : 1
DW_AT_name : BZB
DW_AT_decl_file : 1
DW_AT_decl_line : 20
DW_AT_MIPS_linkage_name: _ZN3AZA3BZBEi
DW_AT_declaration : 1
i.e. no linkage for AZA but I'm not sure how GDB links the methods AZA and
BZB to the class AZA.
