6.0vRC4 - ExceptionLog.obj Linker error when unrelated form removedfrom project

[Daniel Mayo]

Had a bug when building my project that had EurekaLog activated in it.
I removed a form from my project and went to rebuild, and got an error
ExceptionLog.obj not found, then a full build "ExceptionLog.dcu" not
found; and the EurekaLog options appeared to be disabled under the
Project Menu bar.

I had to remove EurekaLog from the Project Options, remove Exception.pas
from the project to get the application to rebuild.

Can you tell me step by step I must do to can reproduce it on an empty
project, please?

Forgive me for posting it so quickly; it just tied me up for awhile when
it happened.

I am unable to repeat this bug right now; I tried a basic project with
two forms, compiled, ran, and then went back and removed one form, but
it worked appropriately. If I see it again, I'll let you know.

Got it again, this time during runtime, not sure how to repeat it though:

Can you send to me the entire .ELF file, please (with the call-stack)?

Ok, where is the .elf file? In this case, no elf is generated, or
updated, in my project direction. It seems as though EurekaLog is
catching IDE errors???

I updated to RC5, and now I can still get the error report, but I can't
copy from the window.. when I try the log locks up. Is there a default
place the .elf should be??? Is there a way to safe a .elf from the dialog?

It's placed in the ($BCB\$Delphi)\Bin folder.

Not, you can only check the "Copy Log Text" check-box.

How I can reproduce it on my PC?

Can you create a source demo able to reproduce it, please?

....or just a step by step points list usable to reproduce it?

What's your direct email address?

Would you like it as the whole .elf (1.866MB) or just an XML of the one
error 823kb?

Trust me, I did try to create a simple app. that could recreate the
error, with no luck.

I'm trying to track down why my code is crashing... Of course, my
dumbed-down object functioned absolutely correctly and the crash didn't
occur.

[Daniel Mayo]

Got it to repeat in something simple using the following 4 files:
Subclass.h subclass.cpp main.h main.cpp
The main form has a button and stringgrid on it. The stringgrid is set
to 1 colcount and 1 rowcount. The button's on click method is defined
in main.cpp

Can you send to me the whole .elf file at: support@eurekalog.com please?

I have try your demo with the last EurekaLog 6 version.

The problem seems to be related to a memory corruption generated by this
specified error. It appears also without EurekaLog.
