* \brief Provides a workaround for GCC Bug 66145.
|
|
* \returns Returns the error message.
|
|
* \throws Throws the current exception if it is not std::ios_base::failure.
|
|
* \remarks
|
|
* - GCC Bug 66145 is "resolved", but the story continues with GCC Bug 85222.
|
|
* - However, the bug finally got fixed for 7.4 and 8.1 so this workaround can be
|
|
* dropped in the next major release which also drops support for older libstdc++
|
|
* versions.
|
|
* \sa
|
|
* - initial bug report: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66145
|
|
* - change introduced in libstdc++ 7: https://gcc.gnu.org/viewcvs/gcc/trunk/libstdc%2B%2B-v3/src/c%2B%2B11/functexcept.cc?r1=244498&r2=244497&pathrev=244498
|
|
* - follow-up bug report: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85222
|
|
* - final fix: https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=259352
