Created attachment 1249199 [details] core backtrace after grace crashed Description of problem: I installed grace plotting software (grace-5.1.25-6.fc24.i686) via yum/dnf install on Fedora 25 (32-bit) OS Workstation Edition without any errors. However, when I open it in terminal via xmgrace I get the following error message: --- xmgrace: malloc.c:2403: sysmalloc: Assertion `(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed. Aborted (core dumped) --- Please help. Version-Release number of selected component (if applicable): grace-5.1.25-6.fc24.i686 How reproducible: always Steps to Reproduce: 1. Open terminal 2. Type xmgrace Actual results: xmgrace: malloc.c:2403: sysmalloc: Assertion `(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed.

Hi, I am running on x86-64 and I do not see that problem. According to a quick search I suspect that there is a memory corruption before that point. The most helpful option would be to run xmgrade with valgrind to detect where does this corruption happens.
I tried running xmgrace with valgrind as suggested. The xmgrace window open now with the following information in terminal. valgrind xmgrace ==19663== Memcheck, a memory error detector ==19663== Copyright (C) 2002-2015, and GNU GPL'd, by Julian Seward et al. ==19663== Using Valgrind-3.12.0 and LibVEX; rerun with -h for copyright info ==19663== Command: xmgrace ==19663== ==19663== Invalid write of size 1 ==19663== at 0x7F9BCAC: intT1_GetFileSearchPath (in /usr/lib/libt1.so.5.1.2) ==19663== by 0x7F969C7: intT1_scanFontDBase (in /usr/lib/libt1.so.5.1.2) ==19663== by 0x7F9824C: T1_InitLib (in /usr/lib/libt1.so.5.1.2) ==19663== by 0x15A788: ???

This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '25'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
