Terminal MacOS Fastlane/Gym/xcodebuild Error 65: GenerateDSYMFile, dsymutil malloc: pointer being freed was not allocated

Question

I'm trying to make an little bash script for automatisation of ipa uploading on itunes. [From Xcode uploading it works fine].

For command:

gym

from Fastlane,some projects are uploading fine, others are failing with log:

The following build commands failed:    
GenerateDSYMFile [...] 
    Exit status: 65

In gym logs:

GenerateDSYMFile [...] 
dsymutil(20223,0x7fff724c3000) malloc: *** error for object 0x610000100000: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/dsymutil failed with exit code 6 

...tried all google solutions....

Answer 1

I've had the same issue.

I've found a reference in this thread, and also here

suggesting that it's the MallocNanoZone environment variable. after changing it (on terminal):

export MallocNanoZone=0

The build successfully completed.
