>Description:
Executable file that compiled by "f77 -r8" makes core dump. ("f77"
without "-r8" option makes no problem)
% f77 -r8 test.f
% ./a.out
Segmentation fault (core dumped)
# "-r8" is meaningful option for "f2c" command. "f77" calls "f2c".
In spite of this, "f77 -c -r8" makes no problem.
% f77 -c -r8 test.f
% f77 test.o
% ./a.out
(This is OK.)
I tested "f77" command with "-v" option. It was found that "f77" command
(without "-r8") calls finally "ld" command with "-e start" option. However,
"f77 -r8" calls "ld" command without "-e start" option.
I think that this feature is meaningful for "f77 -r". However, it's
maybe meaningless for "f77 -r8".
So, the condition for "-e start" option may change from "!r*" to "!r".
>How-To-Repeat:
Always on FreeBSD-2.0(.5)-RELEASE. Never on FreeBSD-1.1.5.1-RELEASE.
