[Bug c++/27359] New: ICE with missing initialization of iteration variable in parallel for loop

[reichelt at gcc dot gnu dot org]

The following invalid testcase crashes the C++ frontend when compiled
with -fopenmp:

==========================
void foo()
{
#pragma omp parallel for
  for (int i; i<1; ++i) ;
}
==========================

bug.cc: In function 'void foo()':
bug.cc:4: internal compiler error: vector VEC(cp_token_position,base) pop
domain error, in cp_lexer_commit_tokens at cp/parser.c:656
Please submit a full bug report, [etc.]

Confirmed, works in C99 mode:
pc64:~> ~/newtest/bin/gcc t.c -fopenmp -std=c99
t.c: In function ‘foo’:
t.c:5: error: ‘i’ is not initialized
