The warning is not correct because
1) The code snippet uses alloca() and variable-size arrays for their
respective purpose:
alloca() for storage that persists until the end of the function, and
variable-size arrays
for storage that persists until the end of the block.
2) In the above sample, all 2 alloca() blocks and 2 variable-size arrays
terminate their
lifetime at the same instruction. There are no instructions after the
bar(...) function call
return; therefore a warning about a possible accidental use of the
type_temp memory after
this point is pointless: the compiler could determine that there are no
instructions any more.
We are asking for an easy way to turn off this warning, so that we can look at
other, useful,
warnings.
This is not duplicate of PR 14236, but rather a complaint about the
implementation of the fix
of PR 14236.
