Bug ID: 28955
Summary: [mips] gas segfault when assembling a simple binary
Product: binutils
Version: 2.38
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: ochi12 at hotmail dot com
Target Milestone: ---
# Environment:
I'm using Ubuntu 20.04.1 on amd64. I've built the last release of binutils
using the toolchain available on Canonical's repos.
# Description:
GAS segfaults when trying to assemble the following file:
```
.global __start
.section .text
__start:
jal 0x8011557c
```
the corresponding command and its output looks like this:
```
$ mips-linux-gnu-as -EB -mips32r2 -O1 -mabi=32 -march=mips32r2 -mfpxx
-mno-shared -KPIC -o /tmp/ccPzROEz.o main.s
main.s: Assembler messages:
main.s:6: Warning: no .cprestore pseudo-op used in PIC code
main.s: Internal error (Segmentation fault).
Please report this bug.
```
The reason I'm passing all those arguments is because that's the way that `gcc`
invokes `as` in order to compile it if one just executes `mips-linux-gnu-gcc
main.s`. This means that this crash occurs even when one invokes `gcc`, and not
`as` directly.
I've first noticed this bug on binutils 2.34, which is the version available on
Canonical's repos. Then I've compiled the latest release like so:
```
export PREFIX="$HOME/opt/cross"
export TARGET=mips-linux-gnu
export PATH="$PREFIX/bin:$PATH"
../binutils-2.38/configure --target=$TARGET --prefix="$PREFIX" --with-sysroot
--disable-nls --disable-werror
make
make install
```
tested it again and got the same results.
