Segfault in t/output_file_exe.t

[eserte]

On a Ubuntu 16.04 I observe the following test failure:

    #   Failed test 'return value 42'
    #   at t/output_file_exe.t line 45.
    #          got: '0'
    #     expected: '42'
    # child died with siganl 11
    # Looks like you failed 1 test of 5.

#   Failed test 'exe'
#   at t/output_file_exe.t line 62.
# Looks like you failed 1 test of 1.
t/output_file_exe.t ......... 
Dubious, test returned 1 (wstat 256, 0x100)
Failed 1/1 subtests 

The same error happens on other smoker systems:

On CentOS8 it's failing for different test scripts (t/ffi_tinycc__add_file_dll.t:...). Here's a backtrace (perl 5.30.1, FFI-TinyCC-0.29):

... it segfaults also on Fedora31. Full list of failing test scripts, on both CentOS and Fedora:

• t/ffi_tinycc__add_file_dll.t
• t/ffi_tinycc__output_file_dll.t
• t/ffi_tinycc__set_output_type.t

However, no segfaults anymore on my Ubuntu 16.04 smoker.

Thanks for reporting this. I am not sure if this is a bug in my module or in TinyCC.
