複数プログラム実行時のCANCEL ALLに関する問題 / Problems with CANCEL ALL when running multiple programs

親プログラムから3つ以上のプログラムを実行したのち、CANCEL ALLを実施した際に、正常にすべてのプログラムがCANCELされていなかった問題を修正した。

Fixed the problem that not all programs were normally CANCELed when CANCEL ALL was executed after executing 3 or more programs from the parent program.

* Fixed the program stack list to be initialized every time CANCEL ALL is executed.

* Fixes the issue with multiple definitions of `cob_unifunc` when linking COBOL modules.
* The following error occurred
```
gcc -pipe  -Wl,--export-dynamic -o prog caller.o callee.o  -L/usr/local/lib -lcob -lm -lvbisam -lgmp -lncurses
/usr/bin/ld: callee.o:(.bss+0x0): multiple definition of `cob_unifunc'; caller.o:(.bss+0x0): first defined here
collect2: error: ld returned 1 exit status
```

fix(tests): Errors occurring in the new version of GCC

Clear the program stack when executing CANCEL ALL.
