int
tre_regcomp(regex_t *preg, const char *regex, int cflags)
{
   return tre_regncomp(preg, regex, regex ? strlen(regex) : 0, cflags);
}

The code is a bit too 'string busy' for me to be comfortable - so I took 
a different approach to look for potential differences in how 32-bit 
versus 64-bit were viewing things. Again, it may not be that the root 
cause is here - but I hope looking at the diff -u of the .i files gives 
someone an good impression of how the data types are being swapped about.

For one example - I had a very old program that had a typedef for 
"typedef unsigned long long ulonglong_t;" that would not parse well. 
When I changed that to unit64_t (as defined in /usr/include/sys/stdint.h)

#ifndef _STD_UINT64_T
#ifdef  __64BIT__
typedef unsigned long           uint64_t;
#else   /* _ILP32 */
#if defined(_LONG_LONG)
typedef unsigned long long      uint64_t;
#endif
#endif
#endif /* _STD_UINT64_T */


All my compilers and os mix (gcc, xlc, AIX and linux) were happy!

So, I am hoping something triggers a thought in the following: (or the 
haystack gets smaller...)
