Hi all,

I posted about this filesystem library issue to the boost list and another user confirmed the problem.

The current thinking is that the boost package needs to be rebuilt with the newer gcc/g++ 3.4.4-3 release for cygwin.  I'm not sure how to identify the current maintainer of the boost package about this, so hopefully posting to this list is sufficient.

Thanks,
Brian

I've been able to create a simple test case...

    #include <boost/filesystem/operations.hpp>

    int main(int argc, char** argv)
    {
        boost::filesystem::path path1("/etc");  // ok
        boost::filesystem::path path2("/tmp");  // boom!
    }

...and it appears to be a problem with creating more than one path object.  I've checked that I'm linking with the correct version of the filesystem library.  I'll post this to the boost user group as well, but would still appreciate any thoughts from this group.

Thanks,
Brian

Hello all,

I found a mirror site that still had 1-5-22-1 and did a full install, but was surprised to find that the fatal error problem I've been having still persisted.  On another machine running 1-5-22-1 this was not the case, and so I (incorrectly) thought the problem may be 1-5-23-2 specific.

What I'm seeing is that within a call to the boost file system library to instantiate a path object, things are blowing up after a free() call in the cygwin dll.  I've attached a gdb trace and cygcheck output for review.  Note that I'm running boost 1.33.1-1, but the problem occurs under 1.33.1-2 as well.

I would appreciate any assistance towards further isolating the problem.

Thanks,
Brian

Subject: Fatal Error w/ cygwin 1-5-23-*
 
Hello all,

I have an app that runs fine under 1-5-22-1, but has a fatal error (see
below) when run under 1-5-23-1 or 1-5-23-2.

I've done a complete reinstallation of 1-5-23-2 (and had tried a newer
snapshot as well), but this has not resolved the problem.  At this
point, I'm not sure what to look for to help isolate the problem.

Any advice?

Thanks,
Brian
