| Summary | 0015518: Compiler crashes when reading PPU file | ||||
| Description | I sometimes have these crashes when compiling a project. Two logs are attached, it is always either the one or the other error. It has something to do with reading or writing PPU files because as soon as I delete all the PPU files of the project it compiles successfully. It only happens on further compilations. Unfortunately I cannot reproduce it on demand and I cannot supply a simple test project (although I've tried to do it). I'm hoping the backtrace will give some info. When I have this error while compiling whole project then I can pinpoint the specific source file on which this error happens. I get this error: ufilesource.pas(451,36) Error: Class or Object types "TFileSourceOperation" and "TFileSourceListOperation" are not related Fatal: Compilation aborted <backtrace the same as in crashlog1.log> However, the TFileSourceListOperation inherits from TFileSourceOperation and the compiler states they are not related. Maybe the info about these classes is read from PPU wrongly. If I remove all the code from that source file except a single "uses <something>;" I still get this error. If I also remove the "uses" clause there is no error anymore. As I mentioned, if I delete all PPU files then the file is successfully compiled. I use FPC 2.5.1 rev. 14644. System is Debian/Sid i386. | ||||

Without additional info, I see no way to find out what happens. |

It's probably the same as this problem: http://lists.freepascal.org/lists/fpc-devel/2010-January/019034.html I've been debugging it, but haven't found the reason yet. I may be caused by the indirect crc stuff I added. I'm fairly close to changing the compiler so it simply stops in case that happens and instead tells the user to delete all ppu files or to recompile everything using -B. The unit reloading logic is really hard to debug/fix (and even harder to automatically test)... |

I can produce a crash on demand now. I say _a_ crash because it doesn't always crash with the same backtrace. I have attached few other logs only to show that all crashes I had before and the ones I can produce now have something to do with either: - TPPUMODULE__LOADPPU or - TPPUMODULE__LOAD_USEDUNITS or - TPPUMODULE__RELOAD_FLAGGED_UNITS. I can cause a crash only when building our full project. It is a Lazarus project and I tried to at least get rid of Lazarus dependency but I couldn't get the resulting smaller project to crash when compiling. How I reproduce it (on Linux and Windows the same way): 1. clean output dir (all ppu, o, etc.) 2. build project -> success 3. change something in interface section in one of the source files - I change parameter type String -> UTF8String: sed -e 's/GetPathType(sPath : String)/GetPathType(sPath : utf8String)/' 4. build project -> crash If I build project again it usually builds successfully, although sometimes still crashes. I did more tests with different FPC versions. I get similar crashes on Windows XP (32-bit). I get crashes when using: - FPC 2.5.1 - FPC 2.4.0 - FPC 2.2.4 - FPC 2.2.2 (only on Windows, on Linux I could not get it to crash). I did not test earlier versions. I will try changing some compiler switches and see if that affects anything. Currently I have: "-MDelphi -Scaghi -Ciro -g -gl -gh -vewnhi -l". I didn't have these crashes before, only since a few weeks ago, so maybe something we changed in our project exposed the bug. Since trying to find recent changes in FPC that might have caused this failed, I'll try to find what changes in our project caused these crashes to appear. |

I can already reproduce at least one crash with the compiler sources, and I know what it's caused by. I spent half the weekend trying to fix it, but didn't succeed yet (one crash was always replaced by another). |

|
Now that the availability of inline info no longer triggers recompilations, such issues will happen a lot less. It's still not perfect, but at least in the compiler such problems no longer occur in the cases where they used to occur |
