I'm running on a 32-bit AIX 5.1 box. GCC 3.3.5 was configured as follows and
bootstrapped.
# This directory was configured as follows:
/home/downloads/gcc/gcc-3.3.5/configure --with-gcc-version-trigger=/home/downloa
ds/gcc/gcc-3.3.5/gcc/version.c --host=powerpc-ibm-aix5.1.0.0 --enable-threads=po
six --prefix=/usr/local/gcc/gcc-3.3.5 --enable-languages=c,c++ --norecursion
When I compile any program that uses -pthread and also throws exceptions,
an "IOT/Abort trap (core dumped)" occurs.
To reproduce this bug, use the following program.
FILE: main.cpp (begin)
int
main(int argc, char** argv)
{
try
{
throw "bug";
}
catch(...)
{
}
return 0;
}
FILE: main.cpp (end)
* When compiled with "g++ main.cpp" the application runs fine.
* When compiled with "g++ -pthread main.cpp" the error occurs at runtime.
* When compiled with "g++ -lpthread main.cpp" the application runs fine.
However, this does not link libgcc_s_pthread which leads to instability in the
real threaded application.
This bug is similiar to #13391, but 3.3.5 did not contain the patches
referenced.
