[Qemu-devel] [Bug 1704638] Re: weak symbol access makes qemu in user mode hang for mips, mips64

2017-12-14 Thread Bruno Haible

This is fixed in qemu-2.11:
$ ~/inst-qemu/2.11.0/bin/qemu-mips testpthsigmask-mips
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault (core dumped)
$ ~/inst-qemu/2.11.0/bin/qemu-mips64 testpthsigmask-mips64
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault (core dumped)

Title:
  weak symbol access makes qemu in user mode hang for mips, mips64

Status in QEMU:
  Fix Released

Bug description:
  A program that is statically linked and invokes a weak pointer should
  crash (because the weak pointer evaluates to NULL).

  With qemu in user mode, for mips and mips64, it hangs. The process
  needs to be killed with "kill -9".

  How to reproduce for mips:
  - Compile the program: mips-linux-gnu-gcc-5 -O -Wall -static -o 
testpthsigmask-mips testpthsigmask.c -pthread
  - Set environment variables for running qemu-mips.
  - ~/inst-qemu/2.9.0/bin/qemu-mips testpthsigmask-mips

  How to reproduce for mips64:
  - Compile the program: mips64-linux-gnuabi64-gcc-5 -O -Wall -static -o 
testpthsigmask-mips64 testpthsigmask.c -lpthread
  - Set environment variables for running qemu-mips64.
  - ~/inst-qemu/2.9.0/bin/qemu-mips64 testpthsigmask-mips64

  When I attach gdb to the process, I see that it is hanging inside
  'gen_intermediate_code':

The behaviour in qemu-2.10 is the same as in qemu-2.9.
