            Bug ID: 28552
           Summary: SIGSEGV when tui is enabled, Linux, source-highlight
           Product: gdb
           Version: 11.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: tui

  Target Milestone: ---

Hi,

When I launch gdb with the tui enabled I get a segmentation fault.

I compiled gdb with source-highlight support in Linux.

Here is the backtrace when I launch "gdb --args gdb -tui ls":

hread 1 "gdb" received signal SIGSEGV, Segmentation fault.

What could be the problem?

Thank you for your help,

> What could be the problem?

I don't know offhand, but considering that the crash occurs
in curses, I would guess some problem with that library.

This definitely works for me.  So without further information
I don't see how we could diagnose or fix it.
