[Bug 697181] Re: DoS: Infinite loop processing 2.2250738585072011e-308

[Steve Beattie]

I've confirmed that marking the double variables as volatile in
maverick's php causes the infinite loop not to get triggered on i386
(and think I understand why that's the case). However, attempts to
reproduce the issue with php from 9.10 (karmic), 8.04 (hardy), and 6.06
(dapper) fail for no apparent reason -- the zend_strtod.c code is nearly
identical between karmic and lucid's versions. Does anyone have an
indication as to what's different that woul cause this issue not to be
triggered on older releases? Thanks.
