ABC error, return code 134

[CambridgeComp]

Hello,

Yosys generates this error :

sh: line 1: 76707 Abort trap: 6 "/Users/me/Applications/oss-cad-suite/libexec/yosys-abc" -s -f /var/folders/f3/3fbt1wk95112sbbw8wbk8t640000gn/T/yosys-abc-QsgndT/abc.script 2>&1
Warning: ABC: execution of command ""/Users/me/Applications/oss-cad-suite/libexec/yosys-abc" -s -f /var/folders/f3/3fbt1wk95112sbbw8wbk8t640000gn/T/yosys-abc-QsgndT/abc.script 2>&1" failed: return code 134.

I've seen that this error is old and known. It is due to big arithmetic and that it will not be fixed in ABC.
But I need some help to fix it and mainly how to find where it is in my sources. How should I proceed ?

Thanks.

Thierry
