#3 IAR Limited Kickstart lastest version

[Link]

This code does not compile with the 5.40.7

There is a linker error :(

Error[e24]: Segment DATA16_AN (seg part no 1, symbol "TA0CCTL2" in module "stopwatch", address [346-347]) overlaps segment DATA16_AN (seg part no 4, symbol "_A_TA0CCTL2_L" in module "timer", address [346-347])

It appears that you are probably using IAR 5.10... unfortunately it appears to be impossible to downgrade IAR or get an older version.
