           Summary: Crash at cp-name-parser.y:220
           Product: gdb
           Version: 7.5
            Status: NEW
          Severity: normal
          Priority: P2

Testcase to reproduce the crash.

GDB crashes when demangling template functions that involve sizeof() in their
names.

Crash message:
cp-name-parser.y:220: internal-error: make_operator: Assertion `i' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.

Platform: Gentoo Linux

Version: GNU gdb (Gentoo 7.5.1 p2) 7.5.1

GCC Version: gcc (Gentoo 4.6.3 p1.6, pie-0.5.2) 4.6.3

Testcase is attached.  I will add a follow-up post if I find an easy
workaround.
