The workaround they used eventua= lly was to compile the crt objects with -fno-asynchronous-unwind-tables. But this is very likely a ld.bfd bug, as there seems to be nothing wrong wi= th the .eh_frame section in crt1.o. Dwarfdump gives me: .eh_frame fde: < 0><0x00000020:0x00000039><_fini> 0x00000020: 0x00000023: 0x00000025: < 1><0x00000074:0x000001a3><> 0x00000074: 0x00000075: 0x00000077: 0x0000007d: < 2><0x000001c4:0x00000297><> 0x000001c4: 0x000001c5: 0x000001c7: 0x000001cd: 0x00000296: < 3><0x000002cc:0x00000311><> 0x000002cc: 0x000002cd: 0x000002cf: 0x000002d0: 0x000002ed: 0x000002f2: cie: < 0> version 1 cie section offset 0 0x00000000 augmentation zR code_alignment_factor 1 data_alignment_factor -4 return_address_register 8 eh aug data len 0x1 bytes 0x1b bytes of initial instructions 7 cie length 20 initial instructions 0 DW_CFA_def_cfa r4 4 3 DW_CFA_offset r8 -4 5 DW_CFA_nop 6 DW_CFA_nop < 1> version 1 cie section offset 52 0x00000034 augmentation zR code_alignment_factor 1 data_alignment_factor -4 return_address_register 8 eh aug data len 0x1 bytes 0x1b bytes of initial instructions 7 cie length 20 initial instructions 0 DW_CFA_def_cfa r4 4 3 DW_CFA_offset r8 -4 5 DW_CFA_nop 6 DW_CFA_nop --=20 You are receiving this mail because: You are the assignee for the bug.=
