Hi Greg,
new/old head versions and different gcc versions do not matter.
The difference is still between 32bit and 64bit.
Printing out the pointer adress and first char before line 498 in ezxml.c
*
fprintf(stderr, " s = %p\n", s);
fprintf(stderr, " s[0] = %c\n", s[0]);
498 while (*s && *s != '<') s++; /* find first tag */
*
yields:
(on 32bit):*
s = 0xb76fe000
s[0] =
*(on 64bit):*
s = 0x7f1179377000
s[0] = <
*
It seems that the contents of the XML-File are not parsed correctly on the
32bit system.
Maybe you have some idea what/where the problem could be?
Best,
David
