preprocessed source code to reproduce bug

Description of problem:

Improperly nested braces and parentheses in a C++ new-style initialization statement cause a seg fault in the compiler.

Version-Release number of selected component (if applicable): gcc-4.6.0-10.fc15

How reproducible: Deterministic.

Steps to Reproduce:
1. compile attached source
  
Actual results:

../visitor-rank-map-inserter.C: In function ‘void<unnamed>::get_xx_type()’:
../visitor-rank-map-inserter.C:100:6: internal compiler error: Segmentation fault

Expected results: Some sort of syntax error.

Comment 1 Jakub Jelinek 2011-10-04 11:21:19 UTC
This only ICEs in 4.5.x (WONTFIX), works just fine with 4.6.0-10.fc15 as well as 4.6.1-9.fc15.
