[Bug 1990729] Re: gdb crashes when run from VSCode

[Lowell Boggs]

I attempted to install this:
   git clone -b applied/ubuntu/jammy-proposed https://git.launchpad.net/ubuntu/+source/gdb

I then downloaded and cd'd into gdb and ran

   ./configure
   make

but got this error:

checking for iconv declaration... 
         extern size_t iconv (iconv_t cd, char * *inbuf, size_t *inbytesleft, char * *outbuf, size_t *outbytesleft);

make: *** [Makefile:1001: all] Error 2


Then I tried to install GMP like this, but it failed

make: *** [Makefile:1001: all] Error 2
gdb: sudo apt-get install GMP
[sudo] password for amida:

E: Unable to locate package GMP
gdb: 

Should I try using the lboggsAmida link instead?  I'll try it.

Title:
  gdb crashes when run from VSCode

Status in gdb package in Ubuntu:
  New

Bug description:
  I had no pre-existing breakpoints in VSCode, then added a breakpoint,
  and used F5 to run the debugger to the one breakpoint.  It crashed
  before it got there.  This is a C++ executable compiled for debugging
  using CMAKE.  I can successfully debug the program using the TUI mode
  of gdb, so I think the problem likes in the vscode interface to gdb.

  /build/gdb-wIRHdd/gdb-12.0.90/gdb/value.c:1731: internal-error: value_copy: Assertion `arg->contents != nullptr' failed.
  A problem internal to GDB has been detected,
  further debugging may prove unreliable.
  Quit this debugging session? (y or n) [answered Y; input not from terminal]
