I'm sorry, I didn't know that ------------------------------------------------------------------------ [2013-02-13 11:32:18] ardbiesheuvel@php.net The preprocessor conditionals in Zend/zend_ini.h test for '__arm' to decide whether _Offsetof() is defined. The assumption is that this define is only set by ARMCC, the proprietary ARM compiler, and not by others (like GCC). However, as Clang does set this define as well (in addition to '__arm__'), the generated code ends up using a macro that is not defined, resulting in the output as reported. Note that rooting out these kinds of bugs is typical for porting to a new architecture, so filing bugs against a stable version is not really appropriate. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
