[SdtElectronics]

• Checked for duplicates

Describe the bug

A simple function definition with noexcept specifier fails with the error function definition is not allowed here

void f() noexcept {}
input_line_3:2:20: error: function definition is not allowed here
 void f() noexcept {}

Expected behavior

Function definition with noexcept specifier should be interpreted correctly.

To Reproduce

Give the input below to Cling:

void f() noexcept {}

Setup

This problem was discovered by @edfink234 in the Cline project. The Cling used by the Cline in service was build upon 1d5536f. I verified it is reproducible on ROOT 6.24/06 as well.

Additional context

Thanks all for the report! This is related to root-project/root#9449, for which we have a PR with some comments pending to be solved here: root-project/root#11265.

This is not directly tackled in the aforementioned PR, but it should be also doable.
