[PATCH 01/29] tests: bump QOS_PATH_MAX_ELEMENT_SIZE again

Posted by Alex Bennée 8 months, 3 weeks ago

We "fixed" a bug with LTO builds with 100c459f194 (tests/qtest: bump
up QOS_PATH_MAX_ELEMENT_SIZE) but it seems it has triggered again.

The array is sized according to the maximum anticipated length of a
path on the graph. However, the worst case for a depth-first search is
to push all nodes on the graph. So it's not really LTO, it depends on
the ordering of the constructors.

Lets be more assertive raising QOS_PATH_MAX_ELEMENT_SIZE to make it go
away again.
