* [Bug pch/60010] New: AArch64: sigsegv in cc1plus using pch without defining TRY_EMPTY_VM_SPACE @ 2014-01-31 15:46 kyle at redhat dot com 2014-01-31 15:49 ` [Bug pch/60010] " kyle at redhat dot com ` (5 more replies) 0 siblings, 6 replies; 7+ messages in thread From: kyle at redhat dot com @ 2014-01-31 15:46 UTC (permalink / raw) To: gcc-bugs http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60010 Bug ID: 60010 Summary: AArch64: sigsegv in cc1plus using pch without defining TRY_EMPTY_VM_SPACE Product: gcc Version: 4.8.2 Status: UNCONFIRMED Severity: normal Priority: P3 Component: pch Assignee: unassigned at gcc dot gnu.org Reporter: kyle at redhat dot com Created attachment 32002 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32002&action=edit add TRY_EMPTY_VM_SPACE define for __aarch64__ Building Fedora with randomize_vm_space on, we've noticed segmentation faults in cc1plus when precompiled headers are used. While I was debugging the PCH internals, Jakub kindly pointed out that AArch64 would probably need a TRY_EMPTY_VM_SPACE define to start looking for free memory at, instead of the default 0. (I suspect that buffer_size needs to be bigger than 32MB now.) Attached is a patch that survived rebuilding our easiest reproducing test-case (wxGTK) 30 times without issue. Thanks, Kyle M. ^ permalink raw reply [flat|nested] 7+ messages in thread
