# Purpose
|
|
#
|
|
# Run a test using the debugger to check that the mbedtls_zeroize() function in
|
|
# utils.h is not being optimized out by the compiler. To do so, the script
|
|
# loads the test program at programs/test/zeroize.c and sets a breakpoint at
|
|
# the last return statement in the main(). When the breakpoint is hit, the
|
|
# debugger manually checks the contents to be zeroized and checks that it is
|
|
# actually cleared.
|
|
#
|
|
# Note: This test requires that the test program is compiled with -g3.
