Fun. The most relevant code is probably in tools/jam/src/regexp.c, and looks like this:
case ANYBUT:
if (*reginput == '\0' || strchr(OPERAND(scan), *reginput) != NULL)
return(0);
reginput++;
break;
you might want to modify it like this:
case ANYBUT:
if (strcmp (reginput, "03") == 0)
printf ("you were supposed to break here\n");
if (*reginput == '\0' || strchr(OPERAND(scan), *reginput) != NULL)
return(0);
reginput++;
break;
then rebuild bjam and set breakpoint on the printf. I am not aware of any assumptions
that 0-9 range is <0x80, but apparently something does not like this, or something else
