no-one here supports Zend.

AFAICT the escaping in that string is wrong - the fact that it did work
the way you want it to is probably sheer luck.
lastly I ran your tests and determined at the least that the 'break'
occur *prior* to 5.2. at a guess it probably changed in 5.0, here are my
results:
# php -r 'echo "php",phpversion(),":\n"; $a = ""; var_dump("\{$s}");' ;
php5 -r 'echo "php",phpversion(),":\n"; $a = ""; var_dump("\{$s}");'
OUTPUT:
php4.3.10-18:
string(2) "{}"
php5.1.2:
string(3) "\{}"

be pragmatic - fix your script :-)
