There's very little help we can give without more detail.  At the very
minimum, we need to know what version of GNU make you're using and what
your build platform is (Windows, GNU/Linux, MacOS, etc.)

Also, we'd need to see an example of the make rule you use to
recursively invoke the sub-make.  There are some common idioms in use
all over for invoking sub-makes which are wrong and can cause behaviors
such as you are describing (not catching errors).

To directly provide the only answer I can based on the information
given, I'm not aware of any bugs or issues where GNU make will ignore
errors and continue on, when use properly.

Cheers!
