Dear all,

The assembler 'as' in Binutils trunk reports an internal error for the
following execution.

The bug was found with AFLFast, a fork of AFL. Thanks also to Van-Thuan Pham.

How to reproduce:
printf
"\x82\x30\x30\x30\x30\x30\x30\x30\x30\x00\x4b\x3d\x3d\x4b\x3d\x3d\x55\x00\x00\x80\x30\x20\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x00\x00\x00\x04\x00\x00\x00\x00\x00\x00\xff\x30\x00\x00\x8f\x00\x00\x00\x00\x00\xbf\x30\x30\x30\x00\x3d\x30\x00\xff\x30\x30\x00\x4b\x3d\x30\x30\x30\x30\x30\x30\x30\x30\x00\x00\x8f\x00\x00\x00\x00\x00\xbf\x30\x30\x30\x00\x3d\x30\x00\xff\x30\x30\x00\x4b\x30\x3d\xbd\x3d\x00\x00\x4b\x3d\x3d\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x30\x40"

a: Internal error, aborting at ../../gas/symbols.c:1432 in resolve_symbol_value
Please report this bug.

The assertion violation was confirmed for trunk, v2.26.1 but not for v2.24.

Best regards,
- Marcel
