[Bug gdb/15650] New: xemacs gdb cleanups.c:264: internal-error: restore_my_cleanups: Assertion '*pmy_chain == SENTINEL_CLEANUP' failed

            Bug ID: 15650
           Summary: xemacs gdb cleanups.c:264: internal-error:
                    restore_my_cleanups: Assertion '*pmy_chain ==
                    SENTINEL_CLEANUP' failed
           Product: gdb
           Version: 7.6
            Status: NEW
          Severity: critical
          Priority: P2

>From my StackOverflow post:

http://stackoverflow.com/questions/17052457/xemacs-gdb-cleanups-c264-internal-error-restore-my-cleanups-assertion-pmy

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!
