Machine Type: x86_64-pc-linux-gnu
Bash Version: 4.3
Patch Level: 11
Release Status: release
Description:
Given two functions wherein only one function sets a RETURN trap. The
other
function will mistakenly call the other's RETURN trap upon it's return.
Repeat-By:
# test trap RETURN if unset from called function
function testU1() {
function _testU1_ret() { echo "${FUNCNAME}" ; }
trap _testU1_ret RETURN
}
function testU2() {
testU1
# when testU2 returns, will it call _testU1_ret ?
}
testU2
# prints the following
_testU1_ret
_testU1_ret
Fix:
For some reason the RETURN traps are not being stacked. Instead, the
current RETURN trap is just overwritten.
