PCD Compiler 4.081 Breaks strlen() function

[johnjohn7188]

PCD Compiler has broken the strlen() function. The loop that iterates through the values in the string loops to an unknown address. See instruction below at address 135A.

Anybody else having this problem?

I see a correct GOTO in this instruction with PCD V4.081. But it may be a position dependent error. Do you see the same behaviour with a minimal test program?

I'll try it out right now.

I also had inserted the strlen() in a complex application, without error...

I experienced some other PCD bugs to be position dependent, they couldn't be reproduced with a simple test program. Such things can happen. You should report to CCS support.

You possibly may not be motivated respectively have enough time to reveal the exact conditions that produce the bug.

My general strategy is to modify the code (in this case the strlen() function) until the error is gone, cut the one line code, e. g. by introducing auxilary variables or moving the increment operation.

Well, my project is about 9000 lines long....
I wrote a library for an LCD that utilizes strlen() to determine how many bytes of a string to print to the LCD. I already reported it to CCS. I'll just have to work around it.

I'm really annoyed that bugs like this still exist in the PCD compiler. It's really eating into my development time....

I have somewhat below 10000 lines now and a lot of bug-workarounds included.

I never thought of, when I started working with PCD one month ago. In between, I considered to change to C30, but now the application is almost finished. Could be worse.

I've also considered changing compilers due to the large number of bugs in the CCS compilers. However, like you, I am almost done with my project, so moving over would require a lot more development time.
