[fpc-devel] valgrind, parsing sym from exe

[Martin Friebe]

Hi,

I am trying to use Valgrind on a executable build with fpc. I get the 
following error (the error was while using callgrind, with verbose output)

==18293== Reading syms from /data/OTHER/laz_trnc/lazarus (0x8048000)

Are there any known restrictions?

- I am using the fpc 22 fixes branch (checked out today)
- compile with either "-g -gv" or "-gs -gv"  (same error in both cases)

- The application I am trying to run under valgrind is lazarus, but as 
for reading the symbol tables from the file, that shouldn't matter?
- Ah yes, and the OS is FreeBSD (whic may be part of the problem...)
- valgrind identifies itself as 2.1.2.cvs (I had to go for the cvs 
version or it wouldn't start at all)

Any idea if there are fixes in later versions of  FPC? Or other compiler 
settings?

Thanks for any feedback

Martin
