I will try to reproduce this error again. I noticed this behavior in my FCGI APP: a client was sending a mal-formed XML content and my app was generating the leaks. My environment: Linux Debian Stretch 64 bits - Lazarus 1.6.4 - fpc 3.0.2. I'm quite impressed with the processing power of fastcgi fcl-web applications: they consume little memory (less than 2 MB per instance) and are very fast to process the requests.

Change your program to the below, and you'll see that it is not leaking memory in the XML routines itself. Michael. In fact, protecting with Try..Except does not generate the leak. That is because you catch the exception object. If you enable line info, you see that the unreleased memory is the exception object and its error message.

It is fast even on Windows+IIS. ;) Best regards, Marcos Douglas ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
[fpc-pascal] -O2 internal compiler errors
When I turn on -O2 I get a never ending stream of internal error 2009112601 which I think is from various inlined operator overloads (didn’t do much testing though). Is this a bug or are they not compatible? Regards, Ryan Joseph ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

If with nothing else, but with a more user readable error message. BTW, yes, it's possible that it has something to do with the inlining. (More specifically, how the inlining interacts with some SIMD register load/store, probably, but this is speculation.) If you're using 3.0.2 you could also try if it still occurs with the SVN trunk version.

[fpc-pascal] installing cross fpc in parallel to systems fpc
Hi, how does fpc and it's makefiles handle the case of installing a cross compiler on a system having fpc installed? The target path will differ and I can set that, but how is the config file .fpc.cfg handled? I'm a bit afraid to mess up the installation not because of fpc but because I'm not really knowing what I'm doing. ;) Additionally there seems to be no compiler switch for changing the configuration file to use, only -n for ignoring it. Is ist possible to name the .cfg on the command line or how would it be done better? TIA, Marc ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
Re: [fpc-pascal] -O2 internal compiler errors
I’m was not able to replicate this right now outside of the project. There appears to be a vast multitude of errors some of which are fixed by removing “inline” and other which I don’t understand right now. When I have some more free time I’ll try again.
