Subject: Backport 43470:
X-Git-Tag: v2.4.4c1~298
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d0dc17031086087358c496418e47a8177e27f26a;p=thirdparty%2FPython%2Fcpython.git

Backport 43470:
Get gcc to do strict IEEE math.  This flag was already used for cc, just not
gcc.  Without this flag, doing pretty much anything with NaNs causes
a Floating Point Exception signal.  This causes the interpreter to quit.
The failing tests this fixes are:  test_long.
This is somewhat equivalent to doing signal(SIGFPE, SIG_IGN).
