[chirp_devel] bitwise struct syntax error

I'm trying to define a block of memory that contains 5 pairs of VFO scan limits (low-high ranges). The storage is the same for the regular 750 channel memories, even though the freq field is the only significant one for the VFO scan limits..

struct channel {   bbcd freq[4];   bbcd offset[4];   u8 unknownA:4,      tune_step:4; ...   u8 unknown24:4,      scramble:4;   char name[7];   ul16 custtone; }; ... #seekto 0x2000; struct channel memory[750]; ... #seekto 0x7DC0; struct { channel low_limit; channel high_limit; } vfo_scan_limits[5];

This gets me:

File "c:\proj\proj_chirp\chirp\chirp\bitwise_grammar.py", line 134, in parse     return pypeg_parse(_language, FakeFileInput())   File "c:\proj\proj_chirp\chirp\chirp\pyPEG.py", line 388, in parse     raise SyntaxError("syntax error in " + u(file) + ":" +   File "<string>", line None SyntaxError: syntax error in input:116:     channel low_limit;

Is this just a bug in the grammar? Or, is my definition of five pairs too complicated for bitwise?

Should I stick to an array of 10 scalars, and do the odd/even math in my code? Easy enough, but not nearly as elegant.

#seekto 0x7DC0; struct channel vfo_scan_limits[10];

Thanks
