Part Number: TMS320F28377D Tool/software: Hi Expert Customer reports the issue with CCS6.2 and v15.12.3.LTS compiler. once the --opt_level set to 0/1/2 the issue can be reproduced, set to off the issue cannot be reproduced below are the actions customer take to reproduce the issue: 1. claim a structure like this: { Var1 Var2 .... } Structure 1 2. claim a structure nest Structure1 like this: { Var1 Var2 .... Structure 1 instance & function handler &Structure 2 address } Structure_2 3. Claim the array Structure_2[N], and write a for loop to select the largest Var1 in Structure_2[N], for example: Temp = 0 for (i = 0; i<N; i++) { if Temp < Structure_2[N].Var1 { Temp = Structure_2[N].Var1 } } 4. set --opt_level to any 0/1/2 level, build and run the project, the variables value in Structure_2 will be changed randomly. 5. if set --opt_level to off, or block the for loop or write the compare statement N times instead of for loop, the issue won't happen. Could you please share some advices to debug this issue? Thanks Joe
