Bug ID: 98320
Summary: Parameter is malformed in the called function
Product: gcc
Version: 10.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: ypn00vb at gmail dot com
Target Milestone: ---
Created attachment 49779
--> https://gcc.gnu.org/bugzilla/attachment.cgi?id=49779&action=edit
main function
When compiling with the -m64 option, one of the parameters passed to the
function is damaged. When compiling with the -m32 option, there is no damage,
everything works.
PS. In the assembler listing, you can see that there is no instruction to move
the stack pointer with the -m64 option. Therefore, the assembler insertion of a
flag register push instruction overwrites the parameter in memory.
