[Qemu-devel] [Bug 1299190] [NEW] Access to /proc/self/exe in linux-user mode |
Date: |

Public bug reported:
This is based on a recent bug in GCC Bugzilla:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60681
It looks like libbacktrace (GCC runtime library used for obtaining stack
traces) uses /proc/self/exe for error reporting. Currently this is
mapped to qemu-arm which effectively disables libbacktrace on linux-
user.
It seems that QEMU already supports /proc/self/{maps,stat,auxv} so
addition of /proc/self/exe may be trivial.
