Comment 2 Jan Kratochvil 2010-06-11 13:20:21 UTC
GDB tries to run pex_run_in_environment("iconv -l") which aborts creating files in /tmp.  GDB should be able to run even with readonly root filesystem.

Comment 3 Tom Tromey 2010-06-21 21:56:20 UTC
Try this:

Posted upstream, PEX_USE_PIPES is OK, pex_run_in_environment is not, thanks:
