The bug reported in LP 243980 is what I am experiencing here (I am
on an amd64 machine). Yet the symptoms you mentioned are different,
and I am not able to reproduce it here.
Actually I realized the following:
$dumpfile("test.vcd"); // dumps to '.vcd' file
$dumpfile("test.VCD"); // dumps to '.VCD' file
$dumpfile("test"); // dumps to 'test' file
So it seems the problem is with parsing the string which contains a
dot '.'
I ran cver through the debugger, I started from src/v_ex.c(4903),
which calls __get_eval_cstr from src/v_cnv.c.
In the first case (ie. "test.vcd") the value of `__exprline' variable
after execution of line src/v_cnv.c:1721 is "\0\0\0\0.vcd" !
So for some reason, the characters before the dot are converted to
nulls !
Also the value of `xsp->xslen' is 64 after execution of line
src/v_cnv.c:1715
In the third case (ie. "test") the value of `__exprline' variable
after execution of line src/v_cnv.c:1721 is "test", and the value of
`xsp->xslen' is 32 after execution of line src/v_cnv.c:1715
I will try to investigate further
