While compiling latest version i get:
In function ‘memset’, inlined from ‘exprDup’ at sqlite3.c:60527: /usr/include/bits/string3.h:82: warning: call to ‘__warn_memset_zero_len’ declared with attribute warning: memset used with constant zero length parameter; this could be due to transposed parameters It seems really wrong.. i checked and the error is also in fossil. Line is:
memset(&zAlloc[nSize], 0, EXPR_FULLSIZE-nSize);
drh added on 2009-09-23 11:54:18:
assert( EXPR_FULLSIZE - nSize == 0 );
To the line above the memset in question and seeing that the assertion fires rather easily. This is a bug in GCC. It appears to be a harmless bug in that correct code is still generated, but a bug nevertheless. anonymous added on 2010-01-11 14:13:28: | ||||
