Discovered and fixed by Sebastien Lorquet after much consternation (2014-12-8). + * libc/stdio/lib_avsprintf.c: avsprintf(): Fix a bug in usage of + va_list on x86. On x86, va_list is a pointer to a single copy on the + stack. avsprintf() calls lib_vsprintf() twice and so traverses the + va_list twice using va_start. va_start modifies that single copy on + he stack so that the second call to lib_vsprintf() fails. This appears + to be an issue with x86 only so far (2014-12-8). |
