Description Michael K Johnson 2021-11-15 13:23:08 UTC 
Description of problem:

When starting prusa-slicer for the second or subsequent times, it crashes immediately with this error:

/usr/include/c++/11/bits/basic_string.h:1058: std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::reference std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::operator[](std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::size_type) [with _CharT = char; _Traits = std::char_traits<char>; _Alloc = std::allocator<char>; std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::reference = char&; std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::size_type = long unsigned int]: Assertion '__pos <= size()' failed.


Removing the .config/PrusaSlicer/cache/PrusaResearch.ini file allows another successful run, after which I have to delete the .config/PrusaSlicer/cache directory again to use the slicer again.

This happens even if I move .config/PrusaSlicer out of the way and start over from scratch with a fresh configuration, so it's not an aspect of my configuration, as far as I can tell.


Version-Release number of selected component (if applicable):

prusa-slicer-2.3.1-5.fc35.x86_64

How reproducible:

Always.

Steps to Reproduce:
1. Start prusa-slicer
2. Exit prusa-slicer
3. Start prusa-slicer

Additional info:

Someone else reported upstream on Fedora 34 as https://github.com/prusa3d/PrusaSlicer/issues/7231 but this issue does not reproduce with their AppImage packages, either of 2.3.1 or their latest beta release, so it's reasonable to consider that it might be related to the Fedora build configuration.
Comment 1 Miro Hrončok 2021-11-15 13:51:32 UTC 
Sounds like this only happens when compiled with -Wp,-D_GLIBCXX_ASSERTIONS.
Comment 2 Miro Hrončok 2021-11-30 13:18:53 UTC 
This should remove -Wp,-D_GLIBCXX_ASSERTIONS as a workaround:

https://src.fedoraproject.org/rpms/prusa-slicer/pull-request/11
https://src.fedoraproject.org/rpms/prusa-slicer/pull-request/12

Could you give it a spin when it builds?
Comment 3 Michael K Johnson 2021-11-30 23:08:49 UTC 
I confirm that https://kojipkgs.fedoraproject.org//work/tasks/6275/79436275/prusa-slicer-2.3.3-3.fc35.x86_64.rpm works around the problem; it no longer crashes.

Thank you!
