Crash when trying to inject

[seboslaw]

Hey,

when trying to inject code while running (in XCode 5.0.1) I'm getting an EXC_BAD_ACESS exception within dyldbootstrap::start(..):

Bundle "InjectionBundle2.bundle" loaded successfully.
dyld: lazy symbol binding failed: Symbol not found: _llvm_gcov_init
  Referenced from: /Users/svogelsang/Development/work/testproj/iOS/iOSInjectionProject/build/Debug-iphonesimulator/InjectionBundle2.bundle/InjectionBundle

  Referenced from: /Users/svogelsang/Development/work/testproj/iOS/iOSInjectionProject/build/Debug-iphonesimulator/InjectionBundle2.bundle/InjectionBundle

The console shows:

Err.. never come across that before. Do you have a small test project that demonstrates the problem you can send through? Email is in the plugin menu.

[seboslaw]

phew....problem is that this is a rather large and complex project. I guess that is also the problem here. I'll try to setup a test project and add all my dependencies one by one and then send you the thing once it starts crashing again.

[johnno1962]

sorry, otherwise I don’t have a lot to go on.. It seems to be something to do with testing: http://stackoverflow.com/questions/566472/where-are-the-gcov-symbols, try editing the bundle project and adding some of the flags they mention. Let me know how you get on.

[johnno1962]

Hi, I’m closing this now unless you’ve found what the problem is.

[kunalbalani]

I have this same problem.

[MaciejGad]

I think that problem is caused by CLang Code Coverage. As mention in http://stackoverflow.com/questions/19290946/clang-code-coverage-mac-os-x-linker-error the best answer is to add following Linker Flags in InjectionBundle.xcodeproj:

-Wall -fprofile-arcs -ftest-coverage

[johnno1962]

Thanks Maciej. Sebastian. is there any chance you can verify this works and I’ll push it onto github.

[seboslaw]

@johnno1962 I'm sorry. I cannot even reproduce my old issue with Xcode 6.1.1. Everything works fine now.

[johnno1962]

Thanks for letting me know. I’ll leave things as they are for now and leave this open for reference.

[fschaper]

Had the same problem. @MaciejGad suggestion worked for me as well. -Wall -fprofile-arcs -ftest-coverage

[luoqisheng]

Had the same problem,-Wall -fprofile-arcs -ftest-coverage worked for me. but after the bundle was loaded,all my viewcontrollers was gone.
