in libXt-1.1.3/Resources.c:976. If I set a breakpoint at lwlib-Xaw.c:831 and choose Syntax Highlighting via menu, I can step into libXt/Resources:976. Near this point the current widget (GaugeWidget)w gets an impossible pointer w->threeD.top_shadow_GC = 0x32. I will invesitage further when I have some time to spare. The GC threeD.top_shadow_GC = 0x32 seems to come from a resource value "50" at Resources.c:767. The XrmResourceList rx has the following values: xrm_name = 336, xrm_class = 824, xrm_type = 21, xrm_size = 4, xrm_offset = -165. What resource this is, I cannot determine. But building XEmacs with Use-Flag Xaw3d disabled resolves the problem so far. So it must have something to do with the 3d athena widget set. I can't reproduce this with the xemacs-21.4.24-ebuild. I'll close this issue. |
XEmacs crashes is a file is loaded with can be syntax highlighted and this feature is active. Reproducible: Always Steps to Reproduce: 1. xemacs .bashrc 2. Activate syntax highlighting in this buffer. Actual Results: xemacs crashes with Program received signal SIGSEGV, Segmentation fault.
