------------------------------------
I have no a patch, I think I can try to fix it :D
> C++ clients crash when exceptions are defined in different IDL

> Key: THRIFT-5507
> URL: https://issues.apache.org/jira/browse/THRIFT-5507
> Project: Thrift
> Issue Type: Bug
> Components: C++ - Compiler
> Affects Versions: 0.14.0, 0.15.0
> Environment: CentOS Linux release 7.6.1810 (Core)
> Reporter: wangguitao
> Priority: Major
>
> 1st, I define a simple test.thrift file, as follow
> *exception MyException {*
> *1:required i32 code;*
> *2:optional string message;*
> *}*
> *service MyResource {*
> *i32 QueryMyResource() throws(1:MyException e);*
> *}*
> generate source code
> *class MyResource_QueryMyResource_presult {*
> *public:*
> *virtual ~MyResource_QueryMyResource_presult() noexcept;*
> *int32_t* success;*
> *{color:#de350b}MyException e;{color}*
> *{_}MyResource_QueryMyResource_presult{_}_isset __isset;*
> *uint32_t read(::apache::thrift::protocol::TProtocol* iprot);*
> *};*
>
> 2nd, I move MyException to other file, as follow
> test.thrift
> *namespace cpp MySpace*
> *include "testc.thrift"*
> *typedef testc.MyException MyException*
> *service MyResource {*
> *i32 QueryMyResource() throws(1:MyException e);*
> *}*
> testc.thrift
> *exception MyException {*
> *1:required i32 code;*
> *2:optional string message;*
> *}*
> generate source code
> *class MyResource_QueryMyResource_presult {*
> *public:*
> *virtual ~MyResource_QueryMyResource_presult() noexcept;*
> *int32_t* success;*
> *{color:#de350b}MyException* e;{color}*
> *{_}MyResource_QueryMyResource_presult{_}{_}isset{_} _isset;*
> *uint32_t read(::apache::thrift::protocol::TProtocol* iprot);*
> *};*
>
> and when client using the interface, client core dump, the core occur in
> funciton uint32_t MyResource_QueryMyResource_presult::read, mark with red line
> case 1:
> if (ftype == ::apache::thrift::protocol::T_STRUCT) {
> {color:#de350b}{*}xfer += ({*}(this->e)).read(iprot);*{color}
> this->__isset.e = true;
> } else
> { xfer += iprot->skip(ftype); }
> the MyResource_QueryMyResource_presult field e isn't allocated memory, so
> client core dump.
