bds2006 bcc32 "hangs" using cpu

[dhoke]

If this still happens with bds2007 bcc32, somebody might wish to report it.
(I haven't bothered to put it in a project to see if there's different
behaviour with IDE compilation.)

The following program source when compiled as simply

bcc32 bcchang_b.cpp
-or-
bcc32 bcchang_b.c

(appropriately) reports errors, then continues to consume CPU beyond my
level of patience to wait for it to stop. (I gave it > 2 minutes.) (With
errors corrected in original context, entire program compiles and links in <
5 seconds for me [after OS has tools in filesystem cache].)

The first error message is slightly different between .c and .cpp versions,
but both runaway with CPU after error messages reported.

========================
#include <stdio.h>

void dump(char *p_p, int n)
{
// int i, j, n_copy = n, n2 ;
int i, n_copy = n ;
char *p = p_p ;
// n2 = 0 ;
for( ; n_copy ; )
{
for(i=0 ; n _copy i < 8 ; i++)
// for(i=0 ; n_copy && i < 8 ; i++)
{
printf("%02x ", *p++) ;
n_copy-- ;
}
printf(" ") ;
for(i=0 ; n_copy && i < 8 ; i++)
{
printf("%02x ", *p+++) ;
// printf("%02x ", *p++) ;
n_copy-- ;
}
printf("\n") ;
}
}

Yes, it hangs TCE2006 IDE as well as the commandline.
Does not hang the BCB 5.51 version.

for( ; n_copy ; )
{
for(i=0 ; n _copy i < 8 ; i++)
// for(i=0 ; n_copy && i < 8 ; i++)

Note that this is a malformed condition.
A simplified hanging version...
all loops and printf seem to be required.

#include <stdio.h>

void dump(int n)
{
for( ; n ; )
{
for(i=0 ; n i < 8 ; i++)
{}
printf(" ") ;
for(i=0 ; n && i < 8 ; i++)
{}
}
}

Please enter this in QC and I will promote it. I have duplicated it.
