I'm running into a memory corruption error with the Windows version of
MPIR, which shows up in the following minimal test case.
Microsoft (R) C/C++ Optimizing Compiler Version 19.25.28610.4 for x64
Compiled MPIR from the latest github checkout earlier this month with this
script:
pushd \mpir\msvc\vs19
call msbuild.bat gc DLL x64 Debug
call msbuild.bat gc LIB x64 Release
popd
copy \mpir\dll\x64\Debug\mpir.dll
Using this source file as a test case:
#include <stdio.h>
#include <gmp.h>
int main(int argc, const char **argv) {
mpz_t x;
mpz_init_set_str(x,"123",10);
mpz_out_str(stdout,10,x);
putchar('\n');
return 0;
}
Compiling like this:
cl /I\mpir /MTd a.cc \mpir\dll\x64\Debug\mpir.lib
And running the resulting program, produces correct output, but on exit
shows a heap corruption, with an error message in a pop-up window that
unknowingly does not allow copy paste, but it's in
C:\Program Files (x86)\Windows
Kits\10\Source\10.0.18362.0\ucrt\heap\debug_heap.cpp
line 996, which is
_ASSERTE(__acrt_first_block == header);
