1181495 - The --debugger_args require a real shell to parse them (can't parse the '=' character)'

Status: RESOLVED DUPLICATE of bug 1151124

(Firefox Build System :: Mach Core, enhancement)

Description

[Nicolas Silva [:nical]]

I am running into this while trying to use valgrind in with unit tests.

The mach command I am trying to use is similar to the one suggested for mochitests here: https://developer.mozilla.org/en-US/docs/Mozilla/Testing/Valgrind (with gtest instead of mochitest).

./mach gtest --debugger="valgrind" --debugger-args="--smc-check=all-non-file --vex-iropt-register-updates=allregs-at-mem-access" Layers.UserData
 0:00.09 /usr/bin/make -C testing/gtest -j8 -s -w gtest
 0:00.11 make: Entering directory `/home/nical/dev/mozilla/objdir/valgrind/testing/gtest'
 0:00.12 make[1]: Entering directory `/home/nical/dev/mozilla/objdir/valgrind/toolkit/library'

 0:00.12 make: Leaving directory `/home/nical/dev/mozilla/objdir/valgrind/testing/gtest'
The --debugger_args you passed require a real shell to parse them.
(We can't handle the '=' character.)
Error running mach:

    ['gtest', '--debugger=valgrind', '--debugger-args=--smc-check=all-non-file --vex-iropt-register-updates=allregs-at-mem-access', 'Layers.UserData']

The error occurred in code that was called by the mach command. This is either
a bug in the called code itself or in the way that mach is calling it.

You should consider filing a bug for this issue.

If filing a bug, please include the full output of mach, including this error
message.

The details of the failure are as follows:
