a fix to SIGBUS in control-panel none

Description michal 2000-03-29 06:49:06 UTC 
'control-panel-3.11' has off-by-one error and writes outside
 boundaries of an allocated memory.  This is causing Heisenbug.  It
 shows, or does not, on apparently identically configured but different
 machines with traces which point to some strange places (like
 internals of glib or gtk).  Likely a Russian roulette with a page
 fault.  This is an actual result from one run under gdb.

 Program received signal SIGBUS, Bus error.
 chunk_free (ar_ptr=0x20000ed10a0, p=0xf5d1afb7f0c2babc) at malloc.c:3038
 3038	malloc.c: No such file or directory.

 Simply lovely!  Piles of "unaligned access" are not even worth to
 mention in the context.

 Attached to this report is a fix  plus a patch to a spec file.
 BTW, if one is going to multiply by a sizeof(char) then adding 1
 outside of this multiplication is not very consistent. :-)
