The author of 'mold' pointed out that with a certain shared library, gdb would fail to find the shared library's name in 'bt'. The function in question appeared at the end of the .so's .text segment and ended with a call to 'abort'. This turned out to be a classic case of calling get_frame_pc when get_frame_address_in_block is needed -- the former will be off-by-one for purposes of finding the enclosing function or shared library. The included test fails without the patch on my system. However, I imagine it can't be assumed to reliably fail. Nevertheless it seemed worth doing. Regression tested on x86-64 Fedora 38.
