I am glad I am not alone. I mailed Michael several backtraces from gdb already.

Hi Michael,

I tried to run the latest fpdoc against tiOPF documentation. I get the following error. Any way I can generate a more detailed error message for you?

./build_core.sh
FPDoc - Free Pascal Documentation Tool
Version 2.3.1 [2008/06/02]
(c) 2000 - 2003 Areca Systems GmbH / Sebastian Guenther,

Writing 3003 pages...
An unhandled exception occurred at $08056FF3 :

$080B4E56
$080497BD
$080499B3

I just tried with my copy of fpdoc for version 2.2.1 (21 April update) and it works fine.

./build_core.sh
FPDoc - Free Pascal Documentation Tool
Version 2.2.1 [2008/04/21]

Done.

Attached is my 'build_core.sh' file. I also tried it by removing the --import and --content lines, but it makes no difference.

Regards,

I recompiled fpdoc with debug information. It gave me a bit more detail, but not much to go on....

I then tried with only a subset of my units and I started having success. In the end I found there is one unit causing the issue. 'tiutils.pas'. Remove that from the fpdoc parameter list and it works fine.

Maybe some formatting has changed or it uses a feature of fpdoc which is not well tested. I have no idea really. I'll go through the tiutils.xml file to see if I can spot something obvious. I'm also going to generate a new skeleton tiutils.xml with makeskel to see what it does. I'll report back.

I couldn't find anything (obvious) wrong with the tiutils.xml file. I also tried with a freshly created tiutils.xml from makeskel and still no luck. :-(

I get the error with building the rtl docs using the makefile: Program received signal SIGSEGV, Segmentation fault. 0x080570b3 in fpc_reraise ()

Well, Vincent Snijders also reported an error when building the RTL docs, but I cannot reproduce it, nevertheless everything is committed, so I would expect that if we use the same code, the crash should occur both with me and with him.

It's very strange. Can you give me the unit that causes this ? Maybe I can then try to reproduce it, and subsequently fix it.

Michael.

And I don't :(

Michael.

I haven't tried generating the FPC docs itself. I'll give that a go.

I send you the attachment in private.

I was able to reproduce the error. But only with the I386 compiler, not with the AMD64 compiler. (I always work with the 64-bit compiler).

The culprit was

  function  _tiFloatToStr(      const AValue : Extended;
                                  const APrecision : integer;
                                  const AFormat : string): string;

Which starts with a _ and not a letter. So all '_' identifiers are now also listed under 'A'.

Took me quite some time to figure this out because of the i386/x86_64 issue :(

Anyway, it is fixed.

Michael.

Why does it work with x86_64?

Vincent

Hell if I know :(

The problem was

  Lists : Arrar['A'..'Z'] of TstringList;

And at a certain point I accessed it with an index '_'. No telling what happens then :(

Michael.

Michael.

Ah, I should have compiled with Range Checks :-)

Vincent

2008/6/2 Michael Van Canneyt :

Strange one, but thank you for you troubles and quick response. I'll test some more seems I now have one more reason to put in a claim for a 64bit work PC. The FPC compiler at included applications just work! :-)
