I do, yes...

But:
- I know eax is correct, because the fall-back (using ^char instead of 
shortstring works:
   -data-evaluate-expression ^char(^pointer(^POINTER($eax)^+12)^+1)
- The fallback is usually needed, if shortstring is not in the 
symboltable at all, but then the expression gives an error. Now the 
expression returns data, but the wrong data...

Strange, the same fpc on windows still works perfect with half a dozen 
different fpc versions (6.3 to 7.2)

It is also possible that my previous fpc trunk on my fedora box was 
build with some debug ino, and now I forgot, and just build it... but 
again on windows I tested with fpc 2.4.2 and trunc, both build with 
several different configs...
