I tried running GDB, version 7.6.50.20130508-cvs (cygwin-special), on Xemacs version 21.4.21 but I get the following error:

/netrel/src/gdb-7.6.50-2/gdb/cleanups.c:264: internal-error: restore_my_cleanups: Assertion '*pmy_chain == SENTINEL_CLEANUP' failed
A problem internal to GDB has been detected,
further debugging may prove unreliable

GDB by itself works fine on Cygwin. On the Cygwin terminal, I did:

g++ -g -o HelloWorld HelloWorld.cpp

to get the executable, and wrote 

gdb HelloWorld.exe

and then

r

and it worked perfectly. I then did 

gdb -v

and the version turned out to be the same as the gdb used by xemacs, so it seems that the error must be related to the interaction of gdb and xemacs, instead of it being a gdb problem?

I found that some people had the same, or similar, issue:

Any ideas? Thanks in advance!

Also, does anyone know where is the cleanups.c file located? I can't even find the netrel folder (it certainly is not located in the / folder in Cygwin).

It is a GDB problem (internal assert is failing), and you should report it in GDB bugzilla if you can reproduce it with current HEAD CVS revision.

the error must be related to the interaction of gdb and xemacs

Emacs interacts with GDB in MI mode. But it's still a GDB bug.
