955 :: Crash on exit (abort)

• filcuc (orginal) [2015-03-02T21:23:34+01:00] view original

  Hi all, i'm testing my project NimQML (https://github.com/filcuc/DOtherSide) on windows. Right now it works fine on Linux however on windows i get a weird crash on exit even if i don't call any function of my library except importing it.

  
  import NimQml
  
  proc mainProc() =
    discard()
  
  when isMainModule:
    mainProc()
    
  Run

  The message that i receive is

  
  This application has requested the runtime to terminate in an unusual way.
  Run

  I tried to debug on windows with gdb and adding debug info. However the crash happen after the mainProc finished so outside the when statement.

  Any suggestion?

  i'm using:

  • mingw32 4.9.1 bundled with my Qt 5.4.1 installation 32bit
  • Qt 5.4.1
  • Nimrod 0.10.2 32bit

  Hi, i solved this by removing the dynlib macro i used for importing a dll symbol and instead compile with nim -l:libDOtherSide -L:path/to/dll. However i didn't understand what happened? maybe is due to dll unloading

  During my testing i removed all my nim code an i got the crash with only one proc that had the dynlib pragma.

  i digged further and now here's the situation:

  • WITHOUT dynlib, compiling with the C compiler and linking my libDOtherSide.dll lib works correctly
  • WITH dynlib, compiling with the C compiler and linking my libDOtherSide.dll lib i get the original error
  • WITH dynlib, compiling with the C++ compiler and linking my libDOtherSide.dll lib works correctly

  So the news is that dynlib seems to work with the C++ compiler but not with the C.

  I checked how i create my .dll with CMAKE and tested it with both SHARED and MODULE flag (http://www.cmake.org/cmake/help/cmake2.6docs.html#command%3aadd_library) but got the same results.

  Any idea?

  I made another round of tests with VisualStudio (instead of MinGW) and everything works correctly
