variable declaration problem

var tmp=0, hex_number[4], word[2]?
var dec_digit=0[5], tmp_word=7[2]?

Backslash in data block cause segmentation fault under linux
Under linux when \ backslash is used in paths in data block it causes Segmentation fault during compilation.
Code to reproduce error:
data map1_pf0_0 {
align 256
image "data\map2" 3 255 4< 256^
}
Result (console output):

make: *** [makefile:15: main] Segmentation fault (core dumped)
It breaks portability of code between windows and linux. As windows support slashes / (however didn't test it with k65, this is just assumption that this will work) in paths maybe it is and idea to state it specifically that it is important to use / for portability in paths.
CLV case
for syntax consistency, it is worth changing o- to v-
constants do not take binary value
[
LSN = 0b00001111
MSN = 0b11110000
]
compiles but has invalid values
PHP aka flag!!
i!! d!! c!! works, n!! v!! b!! works not
break seems to be an implicit keyword ;)
inline break {
data { 0 }
}
doesn't compile
Evaluator and binary numbers case
The evaluator does not work with binary numbers but does not report this during compilation.
[
FOO_MASK = 0b0101
]
gives 0 instead 5
