            Bug ID: 64235
           Summary: Internal compiler error (Segmentation fault)
           Product: gcc
           Version: 4.8.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: wolfgang.roehrl@gi-de.com

Hi,
I would like to post a bug report for the GNU C/C++ compiler 4.8.3.
We use the compiler to generate code for a PowerPC processor.
Invokation line for the GNU C++ compiler:

ccppc -c -x c++ -std=c++11 -Wall -Werror -g -mcpu=8540 -meabi
      -ftls-model=local-exec -msdata=sysv -fno-common -mspe -mabi=spe
      -mfloat-gprs=double -mbig -mmultiple -mno-string -misel -mstrict-align
      -fverbose-asm -fno-exceptions -fno-rtti -fgcse-sm -fno-section-anchors
      -ftemplate-backtrace-limit=20 -G 8 -O3
      -I<some include paths>
      -D<some #define's>
      X.CPP -oX.O


// file X.CPP

struct S
{ double d; };

struct alignas(sizeof(S) S1
{ char d[sizeof(S)]; };


The compiler crashes due to a syntax error ("alignas(sizeof(S)" instead of
"alignas(sizeof(S))") with the following message:

X.CPP:4:26: internal compiler error: Segmentation fault
 struct alignas(sizeof(S) S1
                          ^
