Darian Leung a202ec2caf newlib: Add workaround for printf functions using 32-bit time_t on first call ... sizeof(time_t) was previously switched from 4 to 8, ROM functions that use time_t or dependent types (such as "struct stat") are no longer called due as they still treat sizeof(time_t) as 4 (see commit 24c20d18). However, there is a ROM callpath that was left out. If putchar is the first stdio print related call, the call path will result in cantwrite() -> __swsetup_r() -> __smakebuf_r() -> __swhatbuf_r() using the ROM "struct stat" (where sizeof(time_t)==4). Instead of removing all printf related ROM newlib functions (which will result in increased binary size), this commit adds a workaround to setup the stdio files before any print related calls occur. This results in cantwrite() always returning false, thus the callpath described above never being reached. Closes https://github.com/espressif/esp-idf/issues/9269		2022-08-22 11:28:55 +08:00
