MFC: bring in GCC 2.95.3 + official sjlj exception fixes.

2001-04-10T19:23:41Z

Approved by: jkh The the setjump/longjump exception handling fixes are from GCC 2.95.3.test3 and were removed from GCC 2.95.3.test4 and the subsequent release due to bootstrap problems on HP-UX. However, they were very well tested and fixed major problems on all other platforms. Including all the all the BSD's. OpenBSD and FreeBSD 5-current both use these official sjlj patches. W/o this upgrade the following program segmentation faults if compiled with -O2 (but not -Os or -O or -O0) on 4.2FreeBSD. There are some large C++ libraries where segfaults also occur, even at -O. #include class A { public: A() { printf("c'tor A\n"); } ~A(){ printf("d'tor A\n"); } }; class foo : public A { public: foo() { printf("C'tor foo\n"); throw 8; } ~foo() { printf("D'tor foo\n"); } }; int main(){ try { foo fii; } catch (int){ printf("catch ...\n"); } return 0; }
