#14291: Tests tend to fail in the ext-interp way when split sections is enabled -------------------------------------+------------------------------------- Reporter: bgamari | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: 8.4.1 Component: Compiler | Version: 8.2.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: 13716 Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Description changed by bgamari: Old description:
One issue I've noticed while working on #13716 is that most (if not all) of the tests runs in the `ext-interp` way fail when run inside a tree derived from a source distribution tarball.

The crashes are generally RTS panics or segmentation faults.

One issue I've noticed while working on #13716 is that most (if not all)
of the tests runs in the `ext-interp` way fail when run with a compiler
built with `SplitSections=YES`.
