| Summary | 0035941: Textmode IDE crashes on compiling generic record | ||||
| Description | The textmode IDE reliably crashes with a signal 291 on the attempt to compile this: {$mode objfpc} unit ee_genmat; INTERFACE type generic TMatrix <zz> = record sizex, sizey: integer; end; IMPLEMENTATION begin end. | ||||
| Steps To Reproduce | Simply compile the source from the textmode IDE. | ||||
| Additional Information | It is not a compiler issue, "fpc ee_genmat" works. It's just the IDE which crashes. Compiler settings don't seem to matter. The issue is only with records. When changing the type to object or Class, the problem is gone. | ||||

Hi, I just check using the official release of win32 fp IDE for 3.0.4 and got no crash. I would need to know more about your configuration: What is the target OS are you using, is it win32? The official win32 release of FP prints those lines: E:\pas\check\win32>fp ■ Free Pascal IDE Version 1.0.12 [2017/10/06] ■ Compiler Version 3.0.4 ■ GDB Version GDB 7.4 Do you get the same output? If it is different, where did you get the IDE from? |

Hi Yes, win32. Tested on my office PC and at home with same result. Reinstalled the compiler from the download link on the freepascal site, same result. Yes, same output. I have changed compiler settings, debug/normal mode, several target processors etc. but it always crashes. Deleted fp.dsk, but same result. Wait: I have just started the IDE from a new directory, and it compiles ok. Comparing the fp.cfg files line by line - the problem appears to be -bl. Without that, it works. |

I can not reproduce it either way... |
|
|
The crash indeed only happens if 'Options|Compiler|Browser' is set to either 'Only global browser' or 'Local and global browser' This means simply that the IDE is not able to handle symbols related to generics. Win32 3.0.4 IDE and a recent trunk IDE show the same crash. |
|
|
Yes. Now I can confirm it. |
