I think this is an instance of "eval while blocking input" abort.

I don't think so.  The abort occurs at another place:

#1 0x081897d7 in Feval (form=145945427) at eval.c:2150

This abort occurs if there is a DEFUN with more than 8 arguments.
The one you mean is at line 2000.

But it can't pass through the INPUT_BLOCKED_P check at the beginning
of Feval because it is inside BLOCK_INPUT/UNBLOCK_INPUT in

The default optimization flag "-O2" sometimes reports wrong line
numbers.  I tried with a reproducible "eval while blocking input"
abort (*1) and it reported different line numbers, 2000 and 2150, for
"CFLAGS=-g" and "CFLAGS=-g -O2", respectively.

That sounds like a bug in the compiler. It is no good if we can't trust backtraces. Anyway, know we know what this is.
