The following bug is in all snapshots starting
from April 18. I have only tested this on Alpha linux,
and with FFECOM_FASTER_ARRAY_REFS set to 1.
Run the following through g77:
subroutine a
character*2 string1
character*2 string2
character*4 string3
string1 = 's1'
string2 = 's2'
c
c the next 2 lines are ok.
string3 = (string1 // string2)
call b(string1//string2)
c
c this line gives gcc/f/com.c:10660: failed assertion `hook'
call b((string1//string2))
end
the output from:
/usr/local/egcs-19990418/bin/g77 --verbose -c D.f
is:
