Internal compiler error

[Kent Vander Velden <graphix at iastate dot edu>]

Included is a short program that produces an internal compiler
error with egcs-970907 on a FreeBSD-current machine if
compiled optimized.  If -O flags are left off, it compiles.

  While purning the program down from a few thousand lines...
often this message was given:

tt6.C: In function `int main(int, char **)':
tt6.C:22: internal error--insn does not satisfy its constraints:
(insn 1128 828 829 (set (reg:SI 4 %esi)
        (reg/v:SI 63)) 52 {movsi+1} (nil)
    (nil))
tt6.C:22: confused by earlier errors, bailing out
