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:

"\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"

Please report this bug.
The assertion violation was confirmed for trunk, v2.26.1 but not for v2.24.
Best regards,
