The combination has not been tested before. In the case of ICF, `e.section->getVA(0)` equals the start address of the output section. This can cause incorrect overlapping with the actual function at the start of the output section and potentially trigger a GDB internal error in `dw2_find_pc_sect_compunit_symtab` (presumably because: if a short address range incorrectly starts at the start address of the output section, GDB may pick it instead of the correct longer address range. When mapping an address within the long address range but out of the scope of the short address range, the routine may find nothing - while the code asserts that it can find something). Note that in the case of ICF there may be duplicate address range entries, but GDB appears to be fine with them. Reviewed By: grimar Differential Revision: https://reviews.llvm.org/D89751
