C1060 error (heap exhausted) during compilation by VS2019

[Toshiyuki-Tega]

While installing winim 3.1.1 using nimble with vcc frontend (VS 2019), C1060 error (heap exhausted) occurs at winimx.nim.

Example

> nimble install winim
Downloading https://github.com/khchen/winim using git

Possible Solution

Not sure, but it works fine when gcc (mingw) frontend is used.

Additional Information

  const winimDb = staticRead("lib/winim.db")

In winimx.nim, there's a 2MB file embedded using staticRead. It may be a direct/indirect cause of the problem.

nim compiler from current devel branch is used on Windows 10 x64 Japanese.

It looks like winim problem, also i would not recommend to anybody to use opensource projects which has compressed binary blobs inside, its unsafe.

[khchen]

No, it is not winim's problem. The problem is because that if you load a large by staticRead, the generated C code won't be accepted by VCC. GCC and TCC don't have this problem. This problem is still exsits in nim compiler 1.4.0.

BTW, winim is safe.
