[Bug c++/31338] New: [4.1/4.2/4.3 regression] Cannot apply "!" to complex constants

[reichelt at gcc dot gnu dot org]

The following IMHO valid code snippet is rejected since GCC 3.4.0:

===========================
bool b = !0i;
===========================

bug.cc:1: error: could not convert '#'complex_cst' not supported by
dump_expr#<expression error>' to 'bool'
bug.cc:1: error: in argument to unary !

The C front-end accepts complex constants as argument to "!".
This is related to PR30209.

Btw, the fact that dump_expr cannot handle complex_cst is already
tracked in PR 30896.

> Are you backporting the fix from trunk for gcc 4.2 RC?
Do you even read the patches list?
>From http://gcc.gnu.org/ml/gcc-patches/2007-04/msg01763.html :
I've checked in the patch on mainline.  I'm going to hold off on putting
it on the release branches because (a) it's a big enough change that
there may be follow-on issues, (b) it was broken in 4.1.x too, and (c)
it's an extension.  After 4.2.0 is out, I'll check it in there, if there
haven't been problems.

So the answer to that question is NO.
