Subject: bug#51692: 29.0.50; High CPU in c++ mode. Type finder?
Date: Mon, 08 Nov 2021 13:00:06 -0600 [thread overview]
Message-ID: <yg5v912zd55.fsf@cyc.ece.lsu.edu> (raw)
[-- Attachment #1: Type: text/plain, Size: 355 bytes --]
Load the attached file into a buffer:
./src/emacs --no-init d.cc
Emacs will use 100% CPU on a core while the buffer is visible. CPU usage
goes to normal when switching to another buffer. The attached file is a
reduced version of a much larger file. (The larger file experiences the
high CPU usage only while a certain portion of the code is visible.)

{
if ( indices_segments != opt_segments )
{
for ( int i=1; i<chain_length; i++ )
for ( int t=0; t<opt_segments; t++ )
for ( int inner=0; inner<2; inner++ )
bset_spiral2 << ivec4(i,t,inner,0);
}
buf_uni_common->chain_length = chain_length;
}
{ for(int i=0;i<chain_length;i++)balls[i].push(amt);}
{ for(int i=0;i<chain_length;i++)balls[i].stop();}
