Description Priit Laes (IRC: plaes) 2003-07-09 06:08:24 UTC

when trying to run net-www/straw it gave me a segmentation fault. The problem 
was in dev-python/egenix-mx-base.
First i tried with "-march=pentium3 -O2 -pipe -fomit-frame-pointer 
-fprefetch-loop-arrays -fforce-addr -ffast-math -falign-functions=4" it was 
b0rked.
After reducing CFLAGS "-march=pentium3 -O2 -pipe -fomit-frame-pointer 
-fprefetch-loop-arrays -fforce-addr -ffast-math -falign-functions=4  to 
everyting worked fine

emm .. i can't see any difference between the two CFLAGS ?

Comment 2 Priit Laes (IRC: plaes) 2003-07-16 12:48:24 UTC

I swear i posted another comment about the typo i made.
The broken cflags were: 
"-march=pentium3 -O3 -pipe -fomit-frame-pointer -fprefetch-loop-arrays -fforce-addr -ffast-math -falign-functions=4"

Only -Ox was the difference.
Sorry for inconveniences.

that is correct, it doesn't react well to optimisations. i think this should solve a number of other problems i've had with things that depends on egenix-mx-base! 

thanks for tracking that down!
