#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: | -------------------------------------+------------------------------------- Comment (by hsyl20): Replying to [comment:9 bgamari]:
So I plugged away at this a bit today. I'm increasingly suspicious of 1c83fd814b12754be8af211a387cec906ca198b3 which touches a large amount of ELF linker logic. Unfortunately it's not terribly easy to revert.
I don't know if it is related to this bug but the patch you mention has introduced the [https://git.haskell.org/ghc.git/blob/1c83fd814b12754be8af211a387cec906ca198b... following line]: {{{#!hs oc->info->sectionHeaderStrtab = (char*)((uint8_t*)oc->image + oc->info->sectionHeader[oc->info->elfHeader->e_shstrndx].sh_offset); }}} which may be wrong when there are too many sections (splitSections...). Could you try replacing `oc->info->elfHeader->e_shstrndx` with `elf_shstrndx(oc->info->elfHeader)`? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14291#comment:25 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
