          Issue ID: 15855
           Summary: "a[{for" causes dmd to segfault
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: initrd.gz at gmail.com

Test file:

    a[{for

The first character can be replaced with any valid identifier.

Compiling:

col at col-vm ~> dmd -c test.d
test.d(2): Error: found 'EOF' when expecting '('
test.d(2): Error: found 'EOF' instead of statement
test.d(2): Error: expression expected, not 'EOF'
test.d(2): Error: found 'EOF' when expecting ';' following for condition
test.d(2): Error: expression expected, not 'EOF'
test.d(2): Error: found 'EOF' when expecting ')'
test.d(2): Error: found 'EOF' instead of statement
test.d(2): Error: found 'EOF' when expecting '}' following compound statement
test.d(2): Error: found 'EOF' when expecting ']'
fish: “dmd -c test.d” terminated by signal SIGSEGV (Address boundary error)

Tested on Linux Mint x64 and a recent install of Arch x64, on DMD v2.070.2 and
v2.070.0. The above error uses the fish shell, which generates a slightly
different message than bash on a segfault.
