Hello,
                During testing  with latest master osmo-pcu,  we see that there  is an issue  in decoding of compressed bitmap with make-up code in EPDAN
Input to decoding algorithm:
Compressed bitmap array : 0x7a,0x28,0x31,0xe1,0xf1,0xc1,0x6c,0x32,0x87
Starting colour code : 1
Length : 72

Expected output ( Refer  3GPP 44.060 section 9.1.10):
Expected decoded Length: 304
Expected Uncompressed bitmap: dd c1 48 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 01

Actual output:
Actual decoded length :292
Actual Uncompressed bitmap:  dd c1 48 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

Regards
Prasad
