After opening an xplt file in postview, opening another xplt file (or reopening the same file) causes a segmentation fault.
I have observed the segementation fault when running PostView 1.7.0 (x64), 1.8.0 (x64, glibc compiled with 2.17), and 1.8.0 (x32) on Linux. The segmentation fault does not occur under Windows.
This issue (or one with identical symptoms) was previously reported in the following thread:
In that case, the thread was resolved with a workaround: use a different system with glibc 2.12. I am starting this thread in the hopes of obtaining a solution that does not require the use of an older operating system.
Relevant information for the system on which the segmentation fault occurs:
The last couple of lines output by `strace postview` are:
I can provide the full output if it would be useful.
The following backtrace is provided by running gdb on a core dump (PostView 1.7.0 x64):
Since the SIGSEGV si_addr is 0, I am speculating that fclose() was called on NULL, but I could very easily be wrong.
I am happy to provide further information if it would be helpful.
Best regards,
John Peloquin
