When building a 64-bit version of bpm a compiler error because
sizeof( state_ ) >= sizeof( CLzmaDec )
is false in line 28 of lzma_reader.cpp:
typedef char assert_large_enough[ sizeof( state_ ) >= sizeof( CLzmaDec )? 1: -1 ];
Is this intended to fail for 64-bit compilation ? Using mingw-w64/gcc-9.2 the message in 64-bit compilation the message is:
..\src\lzma_reader.cpp:28:85: error: narrowing conversion of '-1' from 'int' to 'long long unsigned int' [-Wnarrowing]
28 | typedef char assert_large_enough[ sizeof( state_ ) >= sizeof( CLzmaDec )? 1: -1 ];
| ^
..\src\lzma_reader.cpp:28:77: error: size '-1' of array 'assert_large_enough' is negative
28 | typedef char assert_large_enough[ sizeof( state_ ) >= sizeof( CLzmaDec )? 1: -1 ];
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~
while with msvc-14.2 in 64-bit compilation the message is:
lzma_reader.cpp
..\src\lzma_reader.cpp(28): error C2118: negative subscript
Doing a 32-bit compilation succeeds in both cases. Is bpm designed to only work as a 32-bit application ?
