code compile failed: src/library/generator.transpose.cpp:1092:95: error: taking address of rvalue [-fpermissive]

I meet following error:

clFFT-2.12.2/src/library/generator.transpose.cpp:1092:95: error: taking address of rvalue [-fpermissive]
 1092 |         std::string smaller_dim_str = static_cast<std::ostringstream*>(&(std::ostringstream() << smaller_dim))->str();
      |                                                                         ~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~

      |                                                                       ~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~
ninja: build stopped: subcommand failed.

the code is:

std::string smaller_dim_str = static_cast<std::ostringstream*>(&(std::ostringstream() << smaller_dim))->str();
std::string dim_ratio_str = static_cast<std::ostringstream*>(&(std::ostringstream() << dim_ratio))->str();

smaller_dim and dim_ratio are size_t type, these code want to convert size_t type to std::string, can replace following code to address error:

std::string smaller_dim_str = std::to_string(smaller_dim);
std::string dim_ratio_str = std::to_string(dim_ratio);

thank you!
