| Summary | 0001025: alglib makes a wrong assumption for size of bool: is may not be 1 byte | |||||||||||

P. S. I apologize for an accidental duplicate, it is a result of network error, I got a Bad gateway page and re-submitted the issue, however turned out it already got submitted despite the error message. Please close http://bugs.alglib.net/view.php?id=1026 as a duplicate. |

Given that comment to the code explicitly state these asserts can be just removed, perhaps either remove it or at least do this: #ifndef __ppc__ static char _ae_bool_must_be_8_bits_wide [1-2*((int)(sizeof(ae_bool))-1)*((int)(sizeof(ae_bool))-1)]; #endif |
|
(0012037) barracuda156 (reporter) 2024-01-29 18:22 |
And then below: void ae_never_call_it() { #ifndef __ppc__ ae_touch_ptr((void*)_ae_bool_must_be_8_bits_wide); #endif ae_touch_ptr((void*)_ae_int32_t_must_be_32_bits_wide); ae_touch_ptr((void*)_ae_int64_t_must_be_64_bits_wide); ae_touch_ptr((void*)_ae_uint64_t_must_be_64_bits_wide); ae_touch_ptr((void*)_ae_int_t_must_be_pointer_sized); } |
