Do you have a python code snippet which triggers this?

longjmp() is used in only two places:

./Modules/fpectlmodule.c:        longjmp(PyFPE_jbuf, 1);
./Modules/readline.c:    longjmp(jbuf, 1);

Both use it to jump out of a signal handler, which can lead to undefined behaviour (see https://www.securecoding.cert.org/confluence/display/seccode/SIG32-C.+Do+not+call+longjmp()+from+inside+a+signal+handler).
Now, there are two reasons for this behaviour:
/lib/x86_64-linux-gnu/libc.so.6(__fortify_fail+0x37)[0x7f2415de61d7]
/lib/x86_64-linux-gnu/libc.so.6(+0xfe169)[0x7f2415de6169]
/lib/x86_64-linux-gnu/libc.so.6(__longjmp_chk+0x33)[0x7f2415de60d3]

see the __longjmp_chk and __fortify_fail?
That means that Python's been compiled with gcc -D_FORTIFY_SOURCE option option, and the runtime check probably detects this and aborts the program (and the fact that it's a multi-threaded application probably.

The other reason is that it's a multi-threaded application, so if you end up doing a longjmp and restore the environment saved by another thread, you're screwed.

Digging a little deeper:
- in ./Modules/fpectlmodule.c, the longjmp() is actually not used at all (dead code)
- in Modules/readline.c, the jmp_buf is correctly initialized (well, there's a tiny race condition because SIGINT handler is installed before setjmp() initializes jbuf, but it's not worth fixing)

In this case, I'm 99% sure the culprit is:
import pycurl

That's a know bug in libcurl:
"longjmp causes uninitialized stack frame" in libcurl's alarmfunc running gwibber-daemon
https://bugzilla.redhat.com/show_bug.cgi?id=539809

Suggesting to close as invalid.

And the backtrace leaves no doubt:
======= Backtrace: =========
/lib/x86_64-linux-gnu/libc.so.6(__fortify_fail+0x37)[0x7f2415de61d7]
/lib/x86_64-linux-gnu/libc.so.6(+0xfe169)[0x7f2415de6169]
/lib/x86_64-linux-gnu/libc.so.6(__longjmp_chk+0x33)[0x7f2415de60d3]
/usr/lib/libcurl-gnutls.so.4(+0xbb45)[0x7f241528bb45]

The longjmp is in libcurl.
Closing as invalid.
