Hi All, Build of last 10.2-ext fail on Win32 with message : Sysvar 'optimizer_switch' failed 'def_val < my_set_bits(typelib.count)' The problem seems to be in sys_vars.ic (Sys_var_set) :

{ option.var_type|= GET_SET; global_var(ulonglong)= def_val; SYSVAR_ASSERT(typelib.count > 0); SYSVAR_ASSERT(typelib.count <= 64); SYSVAR_ASSERT(def_val <= my_set_bits(typelib.count));

Patch b14e2b04 introduce a new optimizer_switch and now 'optimizer_switch' has 32 values. my_set_bits works with unit32. A new function like this static inline uint64 my_set_bits64(int n) { return (((1ULL << (n - 1)) - 1) << 1) | 1; } might solve this issue. Regards.
