Description of problem:

I just tried to compile package Regina-2.3-1 from 
Redhat Fedora development tree.

The compiler said

1.

./debug.c(308): warning #175: subscript out of range

The source code is

      if (chptr>=chend || outptr >= string->value + BUFFERSIZE)
         break ;

string->value + BUFFERSIZE doesn't exist, suggest

      if (chptr>=chend || outptr > string->value + BUFFERSIZE - 1)
         break ;

is better code.

2.

./extstack.c(407): warning #175: subscript out of range

The source code is

      (*server_name)->value[9] = '\0';

I'm not sure what the fix is for this.

3.

./rexxsaa.c(934): warning #175: subscript out of range

The source code is

            rt->CurrentHandlers->Handlers[RXENV] = handler ;

but

../BUILD/Regina-2.3/rexxsaa.h:#define RXENV       12  /* System
Environment interface */
../BUILD/Regina-2.3/rexxsaa.h:#define RXNOOFEXITS 12

Suggest code re-work.
