Hi,
I am using boost 1.58 in my project. Ran into a crash in the boost filesystem library.
I've included the relevant stack trace at the end of the email. My code is something like this:
boost::filesystem::path fpath(mFilename.c_str());
if (!boost::filesystem::exists(fpath)) {
// log a message and return.
return;
}
auto curr_time = boost::filesystem::last_write_time(fpath); <== crash
The crash is not consistent and happened randomly. I tested the above code in a small test program with just the above code. I made the input file unreadable etc, even then it was able to successfully read the last write timestamp of the file without any issues. Not sure why this particular call would throw an error. Since it's compiled with -O2, the error code is optimized out in the stack trace. Any ideas?
Thanks for your help.
Dk.
