Subject: Test fix: passing bool argument to va_start is undefined
X-Git-Tag: v2.12.0-rc1~662
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=3f322f1a1a1ce2fc1354699f11ac483d7a3cd5fc;p=lttng-tools.git

Test fix: passing bool argument to va_start is undefined

clang warns that "passing an object that undergoes default argument
promotion to 'va_start' has undefined behaviour [-Wvarargs]".

Since va_start's last argument has no known type, the boolean argument
is promoted to 'int', which is not guaranteed to have the same size
as 'bool'.
