Hi, the script below crashes when the zip file contains at least two files. *** glibc detected *** texlua: double free or corruption (!prev): 0x00000000027d10e0 *** ======= Backtrace: ========= /lib64/libc.so.6(+0x79cf5)[0x7f7a57302cf5] texlua[0x78314f] texlua[0x612481] This happens if opened files in the archive are not closed before the next one is opened. The crash happens at the end of the program if the line os.exit(0) doesn't exist. It seems that os.exit() does some cleanup. Since the program does what it's supposed to do I assume that it's not wrong in general to have more than one file opened at the same time.
