The runtime error "ReferenceError: __get_timezone is not defined" occurs when EXPORT_ALL=1

[y-ich]

Hi.

When you use the function tzset in C/C++ and compiles files with "-s EXPORT_ALL=1", the following runtime error occurs.

 ReferenceError: __get_timezone is not defined

I found it in libc-extras.a, but it seems that it is not linked.
How can I fix it?
(I use EXPORT_ALL=1 since I use EXTRA_EXPORTED_RUNTIME_METHODS option.)

My environment is,

1. macOS 10.14.6
2. using latest-upstream
   • emcc (Emscripten gcc/clang-like replacement + linker emulating GNU ld) 1.38.40
   • clang version 10.0.0 (/b/s/w/ir/cache/git/chromium.googlesource.com-external-git.colasdn.top-llvm-llvm--project 10dad95a75592717d2f7c0ebc181fb8a970a8df7)

Thanks.

Please provide a full testcase showing the problem. I tried to compile with that flag and with main just calling tzset() and did not see the problem.

I am sorry for delayed reply.

Today I tried the reproduction code but got no errors.
And I tried the complex case which I found this issue and got different error.
It might be due to the internal state of Google Chrome.

please reopen, i can reproduce with #8995 (comment) and ./repro.sh WHOLE=1 then import datetime;datetime.datetime.now() in the repl
