Okay. The problem with the patch in Comment 27 is that it only partially fixes
the output for DW_CFA_expression. With the partial patch the failing test cases
still fail but now produce...
terminate called after throwing an instance of 'A'
The output now shows...
[MacPro:~/work] howarth% dwarfdump --eh-frame eh-alloca-1.exe | grep -A8
__Z3fooi
start_addr: 0x00001d20 __Z3fooi range_size:
0x000000b5 (end_addr = 0x00001dd5) LSDA address: 0x00002094 Instructions:
0x00001d20: CFA=esp+4 eip=[esp] DW_CFA_advance_loc4 (4)
DW_CFA_def_cfa (ecx, 0)
0x00001d24: CFA=ecx eip=[ecx-4]
DW_CFA_advance_loc4 (7)
DW_CFA_expression (ebp, expr(esp0))
with -O3 -g. Before the partial patch we had....
DW_CFA_expression (esp, expr(esp0))
but we want
DW_CFA_expression (ebp, expr(ebp0))
