#15808: Master sefaults on windows during aeson build when stage2 libs have dwarf enabled. -------------------------------------+------------------------------------- Reporter: AndreasK | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.7 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by AndreasK): The error happens during linking (for TH I assume): The exact moment it happens differs when the memory usage of the compiler changes. If I pass different -H values, different verbosity flags and so on it either fails earlier, later or not at all. When it fails it's always during linking. So I assume there is some issue that arises when GC kicks in during linking, where we then access a pointer that hasn't been updated properly. {{{ !!!
