How did you arrive at 70 doubles and 43 doubles length values? the 70 is the final offset 432 + 16 + 96 =3D=3D 544 plus 16 for the=20 alignment divided by 8 (size of double). I checked this also with the=20 debugger. The 43 is the final offset 232 + 8 + 96 =3D=3D 336 plus 8 for the alignme= nt=20 divided by 8. > 2. It appears that __SPE__ is not accounted for in setjmp.h The SPE is only used in 32-bit processors without a FPU or Altivec unit.=20 So, 256 bytes for the jmp_buf are enough. --=20 embedded brains GmbH Herr Sebastian HUBER Dornierstr. 4 82178 Puchheim Germany email: sebastian.huber@embedded-brains.de phone: +49-89-18 94 741 - 16 fax: +49-89-18 94 741 - 08 Registergericht: Amtsgericht M=C3=BCnchen Registernummer: HRB 157899 Vertretungsberechtigte Gesch=C3=A4ftsf=C3=BChrer: Peter Rasmussen, Thomas= D=C3=B6rfler Unsere Datenschutzerkl=C3=A4rung finden Sie hier: https://embedded-brains.de/datenschutzerklaerung/
