---------------------------+----------------------------
Sometimes a "bad exit 2" happens on ppc64le due to this:
{{{
#!c
/* src/saveload.c:127 */
libGAP_UInt1 libGAP_LOAD_BYTE_BUF( void )
{
libGAP_Int ret;
ret = read(libGAP_syBuf[libGAP_LoadFile].fp, libGAP_LoadBuffer, 100000);
if (ret <= 0)
{
libGAP_Pr(libGAP_LoadByteErrorMessage, 0L, 0L );
libGAP_SyExit(2); /* <------------------------- EXIT HERE */
}
libGAP_LBEnd = libGAP_LoadBuffer + ret;
libGAP_LBPointer = libGAP_LoadBuffer;
return *libGAP_LBPointer++;
}
}}}
(I know it's this call to `libGAP_SyExit()` because I changed the exit
codes to debug this)
This happens for example like this:
{{{
sage -t --long --warn-long 92.8 src/sage/homology/simplicial_complex.py
Bad exit: 2
