compiler lock up "internal error #413 please report to metrowerks"

[jah]

i have the following compiler for the mc9s08rd60dwe
codewarrior development studio for freescale hc(s)083.1 service pk fsicebase ver2

running on win xp + sp2


in a working and established main.c i add the code "while(1);"



and the compiler locks up and will not complete, it compiles w/o the while statement, and this code is used in several of our products for a year. i am using the while statement as a debug aid. the code does odd things when i place it in other areas of the code but it compiles. in the building screen (i only selected the compile icon) the Stop button has no effect?

[jah]

i might also add if i add the following to main.c
int i=1;
while(i);



the compiler takes the statement ok w/o error.

Hello Jah,

I have previously gotten a compiler warning when using the while(1)... construct, but not compiler lockup.  So I substituted the for( ; ; )... construct and this avoided the warning.  I wonder if the compiler does not like there being nothing done within the infinite loop - I actually had some code within the loop.

Regards,

Mac

for( ; ; )

did not work but

while(true==1)

did work

rough and wooly compiler

Hello jah,

I am most surprised that the for() loop construct did not work, since this is used by the CW generated, default main() function, whenever a new project is created.  There has to be another reason.  As a matter of curiosity, what error or warning do you get for this method?

I guess that while(true==1) would be the same as writing while(1==1).

yes the for( ; ; ) did not work but the while(j==0) or while(true==1) works. in some of my other builds there is no error so down stream in the code there is some small black spot that triggers this.

i get "internal error #413" and some reference to a missing glbreg.c file on an F: drive. i never had a F: drive, nor do i want one.

is this only on codewarrior 3.0 and fixed on 5.0????

Hi, jah:

What are your optimization settings? Have you tried turning optimizations off?

It could be that CodeWarrior is having problems while optimizing, and the code optimizes to nothing.

the while(1) causes the compiler is trying to remove dead code and gets into problems.

where is the adj for the compiler.
