Re: [Mingw-w64-public] std::fstream in struct/class - crash

2012-06-11 Thread Deniz Sarikaya

On Windows 8 Release Preview with GCC 4.7.1 (prerelease), this crash
doesn't happen anymore, whether it was the os or gcc.

  Hello,
 
  I don't know why, but this scenario crashes for me with gcc 4.7.0
  rubenvb on Windows 8 x64:
 
  What Windows 8 version. Developer Preview? Consumer Preview? Release
  Preview?
 Consumer Preview


 Try the Release Preview. This might just well be an OS bug.


 
 
  #include fstream
  struct Testfile
  {
  std::fstream t;
  }
 
  You're missing a semicolon here.
 It's not missing in my cpp file ;)
 
  int main()
  {
  Testfile t;
  }

  When using Step Into with GDB 7.4.1 till it crashes, it stops here:
  fstream
  basic_fstream()
  : __iostream_type(), _M_filebuf()
  { this-init(_M_filebuf); }
 
  On what line does it crash? What's the value of this?
 
  What compiler options did you use? It seems some debug info is missing.
  Try
  adding -g3 and make sure no -s is passed when linking.
 Apparently, this crash only happens with -O123 (not with -Os).
 The exact location changes every time, but its always somewhere in
 fstream in the constructors of fstream classes.
 Adding -g3 didn't change anything, also there's no -s.
 The value of this is value has been optimized out.


 OK, that limits it to these options (listed at -O equivalent -O1):
 http://gcc.gnu.org/onlinedocs/gcc-4.7.0/gcc/Optimize-Options.html#Optimize-Options

 If you could determine which one, this would be helpful to find the problem.
 Heck, it might even be -fomit-frame-pointer, but that's also used to build
 the gcc executables themselves. It must be a combination of factors, with
 the most likely being a problem with the prerelease Windows.

With GCC 4.8 (i686-mingw-w64-gcc-4.8.0-20120604-rev-188156) I get this:
The procedure entry point
