Subject: __assert_fail(): remove _Noreturn, to get proper stacktraces
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=2c1f8fd5da3306fd7c8a2267467e44eb61f12dd4;hp=5d893e50b063e67360dabb120b547ba52bfc5b87

__assert_fail(): remove _Noreturn, to get proper stacktraces

for _Noreturn functions, gcc generates code that trashes the
stack frame, and so it makes it impossible to inspect the causes
of an assert error in gdb.

abort() is not affected (i have not yet investigated why).
