Hello,

I use ccextractor -out=report on various files. The report is generated but the execution always terminates with a segmentation fault.

I use a 64-bit Windows 10 machine. I tried with exactly the same result the following three builds:

Downloaded Windows binaries for v0.80 (VS2013)
Rebuilt from v0.80 sources using Msys2 64-bit, statically linked
Rebuilt from v0.80 sources using mingw32 on Msys2 64-bit, statically linked

Examples:

Hey,

just to be sure, is this a Windows or Linux issue (or both)?

Both Linux and Windows.

To be clear, the 3 tests I reported were on Windows with 3 different compilers. I just tried on Fedora 23 with version 0.80 and 0.81 (today's clone of github repo) with the same result.

I attached a gdb report in file segfault.txt. In fact, this is only a final debug trace that crashed the application. Probably easy to fix.

I removed the faulty debug trace, recompiled and successfully run on Windows and Linux.

For the record, I attached a small patch ccextractor.0.80.outreport-segfault.patch.zip

This patch is just here to indicate where the error occurs. It removes the debug trace but you may probably want to properly fix it instead.
