Bug ID: 97073 Summary: Miscompilation with -m32 -O1 -march=i686 Product: gcc Version: 8.4.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c Assignee: unassigned at gcc dot gnu.org Reporter: sirl at gcc dot gnu.org Target Milestone: --- Created attachment 49229 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49229&action=edit Testcase demonstrating the problem. Hi, the attached simple testcase aborts when compiled with every version since gcc-7 (last tested r11-3232). Compiled with gcc-6.3.1 the testcase doesn't abort. Also adding either -fno-tree-ter or -msse2 prevents the abort.
