[Bug c++/15018] New: G++ ICE on struct array element with missing opening curly brace

[burnscharlesn at hotmail dot com]

This bug has been tested to kill the following GCC versions:
GCC 3.3.2 for x86 Linux:
 gcc (GCC) 3.3.2 20031218 (Gentoo Linux 3.3.2-r5, propolice-3.3-7)

GCC 3.3.3 for amd64 Linux:
gcc (GCC) 3.3.3 20040217 (Gentoo Linux 3.3.3, propolice-3.3-7)

uname -a: Linux sivar-laptop 2.6.3-gentoo-r2 #7 Thu Mar 11 23:09:40 MST 2004
x86_64 4  GNU/Linux

Basically the same error for both Gentoo Linux systems:
crash.c:20: internal compiler error: Segmentation fault

GCC 3.0 for HP-UX:
 Configured with: ../gcc/configure --enable-languages=c,c++

Thread model: single
gcc version 3.0

uname -a: HP-UX ux5 B.11.00 U 9000/800 618339393 unlimited-user license

Error for HP-UX:
crash.cpp:20: Internal error: Segmentation fault

----------------------------------------------------------------

The bug does not kill GCC for Redhat x86:
gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-113)
 On it, I get the following compiler error:
crash.cpp:20: sorry, not implemented: non-trivial labeled initializers
crash.cpp:21: parse error before `{'

uname -a:Linux progeny.isu.edu 2.4.25 #2 Fri Apr 9 23:55:35 MDT 2004 i686 unknown

GCC for redhat was the default binary package, so no special compiler flags were
used which cause the problem (unless used by Redhat, obviously)
Gentoo GCC's were compiled with "-march=athlon -O2 -pipe -fomit-frame-pointer"
and "-O2 -pipe -fomit-frame-pointer" respectively.

----------------------------------------------------------------

Every G++ build command I tried will crash, including simply: 
 g++ crash.cpp


The extended (with -v) compiler output on the x86-Linux-Gentoo system is as follows:

I am sure it is similar on all the other architectures, so I'm sure you'll
appreciate that I won't post them here unless someone really needs the info.

[Bug c++/15018] [3.3 Regression] G++ ICE on struct array element with missing opening curly brace

[pinskia at gcc dot gnu dot org]

------- Additional Comments From pinskia at gcc dot gnu dot org  2004-04-20 02:34 -------
Confirmed in 3.3.3 as a regression from 2.95.3, already fixed in 3.4.0 (which should be released today 
or tommorrow) and the mainline.
