A few (more notable) warnings reported by ICC-32:
5.1.4 and 5.2.0-work4:
print.c(45): remark #181: argument is incompatible with corresponding
format string conversion
printf("\\%03u",(unsigned char)c);
-- unsigned int? (also reported by splint)
5.2.0-work4: ^
lapi.c(1147): remark #593: variable "p" was set but never used
Proto *p;
^
-- though suppressed by UNUSED(p) or LUA_USE_APICHECK
related splint warnings:
5.2.0-work4:
src/print.c:189:2: Format argument 1 to printf (%d) expects int gets lu_byte:
f->numparams
src/print.c:188:11: Corresponding format code
src/print.c:190:2: Format argument 4 to printf (%d) expects int gets lu_byte:
f->maxstacksize
src/lstrlib.c:761:31: Format argument 1 to sprintf (%d) expects int gets
unsigned char: ((unsigned char)(*s))
src/lstrlib.c:761:27: Corresponding format code
src/lstrlib.c:763:33: Format argument 1 to sprintf (%03d) expects int gets
unsigned char: ((unsigned char)(*s))
5.1.4:
f->nups == 1
print.c:175:2: Format argument 1 to printf (%d) expects int gets lu_byte:
f->numparams
print.c:174:11: Corresponding format code
print.c:176:2: Format argument 4 to printf (%d) expects int gets lu_byte:
f->maxstacksize
print.c:174:25: Corresponding format code
print.c:176:46: Format argument 6 to printf (%d) expects int gets lu_byte:
f->nups
Also, FYI, MSVC++ 2010 (x64) luavs.bat gives warnings below. (There
are no such warnings in mingw-64.)
