It turns out the the work around is not working 100% of the time, but its better then before. If anyone was figured out how to fix this please add a comment saying what you did to fix it.

We just updated to RHEL 7.2 and are using 3.3.12 ddd and found that this bug is happening to us too. However; if we Edit->Preferences, Select Tab Source, and select Show Position as Text Characters vs. the default Glyphs the core stops. Also, if LANG unset or set to C it works with Select Tab Source as Glyphs. But we need to set LANG=en_US.UTF-8 for Sybase to work.

We noticed that some adobe symbol fonts are missing. Is there is some X11 font package required? The SA are only installing packages as needed vs. installing everything. We never had this problem on the old RHEL 5 boxes.

SourceView.C: In function `static void SourceView::UpdateGlyphsWorkProc(void*, XtIntervalId*)':
SourceView.C:8724: assertion `*proc_id == *id' failed

Unfortunately, this assertion doesn't dump the values that it is failing, and the build is optimized, and unavailable from the core:

(gdb) frame 3
#3 0x00000000005a53d1 in SourceView::UpdateGlyphsWorkProc (client_data=0x8aa218, id=<value optimized out>) at SourceView.C:8724
8724 assert(*proc_id == *id);
(gdb) p id
$1 = <value optimized out>
(gdb) p proc_id
$2 = <value optimized out>

Not sure if the value is available from the regs, since it looks like %rdi gets clobbered by the assert call:
