Summary0001282: var_dump() of integers > 32 bit is broken
Description

This is 64 bit Windows, PHP and Xdebug. It seems any integer with more than 32 bit value are truncated to 32 bits in Xdebug's var_dump(). Examlpe uses PHP_INT_MAX but any value outside of 32 bit integer range is affected.

Steps To Reproduce

D:\devel\rgu-bars-forms>php -r "var_dump(PHP_INT_SIZE, PHP_INT_MAX);"
Command line code:1:
int(8)
Command line code:1:
int(-1)

D:\devel\rgu-bars-forms>php -d xdebug.overload_var_dump=0 -r "var_dump(PHP_INT_SIZE, PHP_INT_MAX);"
int(8)
int(9223372036854775807)

Additional Information

I can't easily see what the problem is by looking at the code, so I'm going to have to get back to this once I make it home and have access to Windows again. On Linux, this works "just fine"™.

I may be wrong, but after quick search line 1031 in xdebug_var.c may be the cause (https://github.com/xdebug/xdebug/blob/master/xdebug_var.c#L1031): on Windows to print long long "%lld" is required.

Sure, but I'd like to test it before committing something like that. And Windows uses some other format specifiers too in places. I'll get to it :-)
