|
# In a nutshell: the function 'beta' ends with a call to 'abort', which
|
|
|
|
|
# is a noreturn function. So the last instruction of 'beta' is a call
|
|
|
|
|
# to 'abort'. When gdb looks for information about the caller of
|
|
|
|
|
# 'beta', it looks at the instruction after the call to 'abort' -- which
|
|
|
|
|
# is the first instruction of 'alpha'! So gdb uses the wrong frame
|
|
|
|
|
# information. It thinks that the test program is in 'alpha' and that
|
|
|
|
|
# the prologue "push %ebp / mov %esp,%ebp" has not been executed yet,
|
|
|
|
|
# and grabs the wrong values.
|
|
|
|
|
#
|
|
|
|
|
# By the nature of the bug, it could pass if the C compiler is not smart
|
|
|
|
|
# enough to implement 'abort' as a noreturn function. This is okay.
|
|
|
|
|
# The real point is that users often put breakpoints on noreturn
|
|
|
|
|
# functions such as 'abort' or some kind of exitting function, and those
|
|
|
|
|
# breakpoints should work.
