#15696: Derived Ord instance for enumerations with more than 8 elements seems to be incorrect -------------------------------------+------------------------------------- Reporter: mrkkrp | Owner: (none) Type: bug | Status: patch Priority: highest | Milestone: 8.6.2 Component: Compiler | Version: 8.6.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect result | Unknown/Multiple at runtime | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D5196, Wiki Page: | Phab:D5201 -------------------------------------+------------------------------------- Comment (by osa1): I did a little bit of debugging for the segfault problem. I'm wondering if I'm triggering some other bug, because the segfault is happening during GC: {{{ p=p@entry=0x756150, ret=ret@entry=0x0) at rts/RtsAPI.c:530 #10 0x00007fdcea6433ec in hs_main (argc=<optimized out>, argv=<optimized out>, main_closure=0x756150, rts_config=...) at rts/RtsMain.c:72 #11 0x0000000000749560 in main () }}} The info table pointer is wrong: {{{
print info $1 = (const StgInfoTable *) 0x72 }}}
