Issue 41976 added ctypes.util._is_elf() to filter out linker scripts such as
"libc.so". The PR was backported to 3.7. _is_elf() assumes the trace result has
absolute paths that can be opened, but Matthias is getting the relative
filename "liblibc.a" in the result. Whatever the reason, I think if the file
can't be opened for reading, then _is_elf() should just return False. For
example:
def _is_elf(filename):
"Return True if the given file is an ELF file"
elf_header = b'\x7fELF'
try:
with open(filename, 'br') as thefile:
return thefile.read(4) == elf_header
except OSError:
return False
