Bug ID: 45190
Summary: arch/x86/entry/entry_64_compat.S: Assertion `OS.tell()
- Start == Layout.getSectionAddressSize(Sec)' failed
Product: libraries
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: MC
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Building above file in the linux kernel triggered the assertion failure. The
reason is due to the following code pattern
$ cat bad.s
.macro ALTERNATIVE newinstr
.skip 144f-143f,0x0
.pushsection .altinstr_replacement,"ax"
143:
\newinstr
144:
.popsection
.endm
.section .entry.text, "ax"
ALTERNATIVE "jmp .Lint80_keep_stack"
.Lint80_keep_stack:
$ gcc -c bad.s
$ echo $?
0
