Sb: #printf problem

Has anyone else noticed a problem with the printf() family? The following code
fragement works fine by itself, but in a large program it doesn't:

   switch (fmt){
     .....
     case 'H': sprintf(buff,"%X",value);
               break;
     case 'h': sprintf(buff,"%x",value);
               break;

     ....

The entire format loop works fine--expect when the %X format is used. In this
case a single 'x' is printed. However, %x, does work alright. I've put a bunch
of debug code (printf()s) in the real program and the printf() react the same
way. For some reason, uppercase hex doesn't work. However, when I just extract
the code out and stick it in a test program, all works alright. I've really
pulled my hair on this one--even checked the crc while the program is running.
No luck. I've cobbled a work-around for now by using %x and then converting the
string to uppercase if fmt=='H'.

Either there is a bug in sprintf(), or my program is cobblering something. Any
ideas?
